Well since I'm 95% sure I'll have a N/A, I want to make sure it sounds alright, not real loud, but enough to hear, with a deep toned sound.

So I was wondering, as I look through the aftermarket sites, most of the ones either dont specify or say for the turbo model. Do the turbo cat-back systems fit on the N/A? And whats a good option for a louder-than-stock-but-not-ricer-loud muffler that takes well to later performance upgrades? What about downpipes and such? I believe I'll need a cat, and a high flow cat will pass emissions eh? I can't weld so I'm stuck in a hard spot I suppose.

Glass pack 14/16 inches.
Keep the cat. Without it you will run really rich.
Not to mention get shitty gas mileage. The na models don't burn as efficiently as the turbo's do.

Cool, thanks for the tip. So keep the cat, good, less work, but would a high-flow cat be better? I heard an aftermarket downpipe helps loads also, because the stock is crush bent or something, or mebbe just really crappy? (I dunno, when I went to work on my friends it already had header-back and we upped it to a 4inch turbo-back no cat)

yo if u got an na i just put a cat back wit a high flow cat and flowmaster muffler its not to loud nide deep sound and to get past the running rich thing i had my timing and injecter pulse's done and acid bath my throttle body and it cost bout 1100 for all and its a freaking rocket bro

never heard about acid bathing the throttle body and that other stuff sounds a little out of budget for a little while so for now I guess I'll just do a cat-back, and an intake (assuming its not already done hahaha)

thanks!

its not to bad i dropped 1100 and went from like 15's to a 14.1

Sounds good, but I'm probably gonna not run it very hard and use it as a DD for a while until something major happens and I end up doing a swap.

So as just a cruiser, I just want it to sound nice, look decent and have a good cd player hehe.

So I was probably gonna get some new rims/tires, juice up the sound system a bit, and do something with the exhaust to give it a bit more presence.

Once I go for the swap, I'll go all out, top and bottum end, and probably get custom interior work and everything, turn it into a show car.

thts tight dude i thought of tht butt i wanna turn one into a dedicated drift car

I bet your antenna doesn't work. If it does you're lucky.

I'm telling you bro. Glasspacks with a dual tip and you will love the purrrrr the engine gives you and then you run them nice and hot and hose them at the car wash. Ya baby. Adds that low end grumble.

And the beauty is you can stay with the stock pipe. This is a pleasent alternative for arounf 50 bucks till you find exactlly what you want.

Sounds great to me, especially the price. Normally require welding? As I said, I dont have the knowledge or tools to weld heh heh. I've always liked glasspack though, but arent they usually crazy loud?

And about the antenna, no worries, my friends didnt work either. I can fix it easily, and besides I never really listen to the radio, I listen to cds and it says someone actually did put a cd head unit in. Not sure about the rest of the speakers but I've done a complete audio system in a supra before, so I'll manage.

If you think thats bad, the suzuki I just sold, when I put the 300$ head unit in, the antenna wire barely wouldnt reach and I couldnt be bothered with the extension hahaha.

When you get the pack welded on. Hold the tips to the end that you like while the car is running and choose by sound. Ya they're loud but not obnoxiously loud. Just enough to let everyong know you have a modded exhaust.

Edit. Anothr 50 dollar goodie is an msd blaster coil. The stock coil throws 12 volts the blaster throws 22 volts. Coupled with msd wires and your'e in the good cat. 100$ A walbro fuel pump with w 12 volt wire in. Cheap upgrades bro 1 at a time. Do the easy ones first.

Pray it has a good starter. you may want to go to the stealership and purchase a t.s.r.m
touyota supra repair manual. F_uck chilton and haynes. The tsrm is the bible dude.

isnt the tsrm online? i think i have it bookmarked.

Oh, and about getting one welded on... Like I said, I can't weld... been looking for bolt-ons. But the glasspack sounds like a winner, I could probably get one of my family there that lives nearby, they can all weld haha.

the first thing imma do is plugs, wires and fluid changes for sure. I'll have to see what condition the thing is in before I prioritize. Its likely by the way its been done up on the inside that someone already has an aftermarket exhaust, and possibly some other stuff too.

Thanks again for the idea, I remember we had a jeep CJ-5 with a pretty monstrous V8 in it, with headers-back and dual side exit exhaust with those huge red glasspacks. That thing sounded like it wanted to take other cars, bend em over and... well you get the point hehhehe.

I'm not a fan of glasspacks... especially not on the N/A. The thing that bugs me the most about all the various exhausts I've heard on the N/A are that *typically* the better they breathe the raspier it sounds. Also, they typically get louder as they wear in and the fiberglass breaks up. So if you do install one and it sounds exactly how you want it to sound ton expect it to last.

Yes, welding is a given on most car exhaust work. If you supply all the parts most exhaust shops around here will weld everything together for you pretty cheap (under $100).

I've got a 2.5" cat back with no resonator and a Borla ProXS muffler. I really like the sound. Personally it could be a tad quieter, but my friends all like it as is.

Borla is good stuff. But he's wanting cheap upgrades I took it.

yeah i've heard some bad things about glasspacks too but I don't have enough experience to know

and I did an entire cat-back on my suzuki by getting custom bent pipes at a napa, and just clamping em all together. haha it wasnt great but, well, this place is... well lets just say it was the only option I had.

Borlas aren't that expensive... I've got one here I'd let go of for $65 +shipping. I wanted something I could be sure would last. The one thing I still want is to add a 2.5" TurboExhaust resonator.

welp, mebbe when i get situated and hopefully am able to get internet soon, i may be interested in the borla la la, from what i've heard everywhere, they are excellent.

If I went to pick a muffler right now it would probably be a split between borla, flowmaster, and the N1 (I heard its good)

Here's what my N/A sounds like:

Sound clips: 1 (http://www.fadingworld.com/Supra/Borla/1%20outside_short_takeoff.mp3) 2 (http://www.fadingworld.com/Supra/Borla/2%20outside_toward_decel_idle.mp3) 3 (http://www.fadingworld.com/Supra/Borla/3%20outside_wot_flyby.mp3) 4 (http://www.fadingworld.com/Supra/Borla/4%20outside_startup_idle_rev.mp3)
EDIT: In the last clip my friend is walking around the car, hence the varying tone and the sound of the intake.

Excuse the gravel sound... still had my studs on.


You can find some more exhaust sound clips here (http://www.supramania.com/forums/showthread.php?t=40282).

definitely sounds good on yours, but a little quiet, i dunno if its because of the way it was recorded or if its actually supposed to be that quiet. borla right?

and that other link, i really like that one with the magnaflow resonator haha, thats about on par with the sound I'd like. although if yours was a little louder, i think id like it more

Quiet? Ack... I hate how loud it is. I'm planning on adding a resonator when I get the cash.

I'll take a car that's quiet and deep over one that sounds like it's running on beans. Most mufflers on our cars make some of the worst sounds.

welp probably do a borla then haha

welp probably do a borla then haha

Oh no, no, no... you want loud. You should look into a setup like the one on the MKIII I'm currently working on: No cat, no resonator, 3.5" pipe ALL THE WAY! It's so loud it's literally painful! No that's... what's the term? Dope? Yeah, it's dope!

I had another MKIII owner helping me tune it today. At one point I said, "You mind driving back to my place? I need to grab some ear plugs". He said "Only if you've got another set". In the end it still wasn't enough. My ears are still ringing and we both had horrible headaches.

i dont want overwhelming loud hahaha

i'm sure yours is enough to drive without ear plugs

and i know about loud, i helped my friend with his 89 turbo, turbo-back 4inch all the way, no cat, 4inch straight through muffler

WHAT!? I'm not kidding... ears are still ringing. I think it caused some damage... UGH!

The kids around here typically have exhausts that are a little louder than mine... but they all sound like absolute crap. Mine's loud enough to hear in the car and a lot louder to those outside. My wife knows when I pull up to our apartment complex. Like I said, it's louder than I want, but my friends like it.

Personally, I'd prefer an obscene amount of power and a dead silent intake and exhaust... but at least it doesn't have that putt-putt, craptastic sound all the kids in their Honda's (and most N/A MKIII's) sport with their aftermarket exhausts. It's also got alot less of the typical 2000RPM drone than any of the other MKIII's I've ridden in.

So, while I like it, it may not be to your liking. You can always weld in another muffler if you don't like your initial choice, but I put a lot of research into choosing mine so I could avoid the hassle and I recommend you do the same. Listening to exhausts on similarly built engines helped (3 series BMW's with I6 engines and MKIV Supras). Don't rely on clips which are filmed from the back of the car right after starting, look for footage with the car being driven, filmed from both inside and out.


NOTES: My friend who was recording was, at the closest, 20' from the car. We didn't just set the camcorder behind the car and rev the engine a couple times... that's no way to show how an exhaust sounds. The car was up to normal operating temps and I was driving up and down a 4 block strip of residential road at everything from idle to ~4000RPM. The recording was made after the muffler had broken in a bit, about a month after install. After breaking in it's a fair amount louder than when it was first installed.



EDIT: Oh and a Turbo with a 4" exhaust is nothing compared to an N/A. Turbos actually quiet things down and smooth out the sound a fair amount. I had to drive my car for a day with an open down pipe... OUCH.

yeah its hard to find sound clips or experience the sound, so I guess I have to go on reviews to start with, then trial and error.

so yeah i want loud enough to be noticed, a nice purr, but not something thats gonna have people going "what the heck is that racket!" or "damn ricer!" hahaha

Hello. I thought it was kinda quiet also cre.
It sounded good.

I have always just used glasspacks. Pretty much on whatever I was driving.
I like the sound of my supra with it on. It's only overly loud when you drive between tall buildings and then it's still kinda fun.

There's a kid down the road from me who has an eclipse and a parts car also. He put some kind of exhaust pipe on it and it sounds like ass. I can't wait to get my supra running. I'm going to waxxx some mitsubishi ass.

Damned kids..... :aiwebs_01

Now what is that supposed to mean???
By the way. can you produce pics of this 65$ exhaust you would part with?

See i don't have a DL. SO I have to watch for the rollers and always wear my belt and all that. I also have to watch my exhaust. It sounds mean dude. When it runs.

Now what is that supposed to mean???

LOL... Uh, nothing.

By the way. can you produce pics of this 65$ exhaust you would part with?

Don't have it here with me at work, but yeah, when I get home later tonight I'll take a couple.

See i don't have a DL. SO I have to watch for the rollers and always wear my belt and all that. I also have to watch my exhaust.

Driving without a license? Naughty, naughty... I hope you've at least got insurance.

I have insurance. I wouldn't roll without it.
We get high priced insurance. My wife you see needs uninsured driver along with everything else so if I wreck my $hit. I just borrowed it from my wife, lol. Really though. Rolling without coverage is unforgiveable in my eyes.

I mean I figure if someone hits me and they don't have coverage..., well I should get to take it out of your hide. Then and there. That's the only satisfaction you're going to get. Because the judge can order him to pay. But that doesn't mean jack.

Unfortunately, insurance companies are allowed to disclude unlicensed driver from policy coverage... read the small print. ;) I hope your policy would still cover you.

Yeah, I do agree that driving without insurance is flat out rotten. The same goes for driving without enough coverage... Although I blame insurance companies more for that.

My policy which covers 4 cars includes medical coverage (not required in CO), additional coverage and uninsured motorist. It's still quite a bit cheaper than full coverage, but I may move a couple of our cars to full coverage soon.

Ya. my wife's the coooolest.

so i believe i need a new cat, what brands are the best? bolt on or universal? ill take pics so you guys can see. i live near summit racing but all theyve got is magnaflow and catco or something.

magnaflow. it'll probably be a bolt on but your muffler guy will and can weld it.

You should also check out, www.horsepowerfreaks.com

it says direct fit, what do you think?
but theyve also got universal, soo.....


Converters made just for your application.
These MagnaFlow Direct-Fit catalytic converters are designed for easy bolt-on installation for the professional installer. Welding, cutting, and tube-bending equipment are not required. They feature a ribbed body that minimizes expansion and distortion when the converters heat up. The ribs form a channel that protects the cushioning mat from direct exposure to exhaust gases, and they hold the ceramic catalyst in proper alignment. These converters use a monolithic honeycomb catalyst. The ceramic coating is designed for maximum flow and surface area, and the coating method is strictly controlled to maintain exact specifications. An improper coating could result in flow restrictions or an emissions test failure. These converters are designed to exact OE specifications, and are available for the most popular vehicle makes and models.


heres pics of my cat, at least i think its my cat, please dont flame me if its not.

and thats my new exhaust, it was on there when i bought it, let me know what you think

Someone welded scrap metal together to look like an exhaust pipe.

That looks like 3 inch. You want to reduce down to 2.5 inches. Anything more on an na is overkill and you will probably run rich.

Find a shop and have it redone. Just get a flowmaster. I say this because it's easier. I like glasspacks myself but that's a recent topic of debate.

You're looking at around 150/200 dollarish. It should be closer to 150.

This scares me a bit. I gotta ask for pics of the engine bay.

We're going to get you straightend out dude.

dayum.
i can prob do that.
i want a sweet sound though, low growly and purring like a giant cat.
i have a bunch of pics on my noob thread. i dont know if i hav the one of the engine bay up yet though.
hows the cat look?

Are you serious, lol. It's thrashed. Your entire exhaust pipe is wrecked.
You'll notice a huge improvement after you repair it and it's one of the less expensive band aids you'll be getting. This is a must.

Still want engine bay pics:rock_band

so i need:
-cat
-muffler
-downpipe? i dont know what that thing is called.

Look man. Unless you have a welder and can use it. You are making way too much of the exhaust. You're sweating something that you are going to have to pay someone else to stress over. Throw a 16 inch glass pack on and inexpensive catalytic converter. The cat burns up the excess fuel that would bleed through and make you run rich. Pick out a tip and call it good.

You can spend the big bucks later. Right now we have to fix you up and for cheap.

I thought my engine bay was bad when I got it you win hands down.
The upside is it looks like dirt and not oil. Big good thing right there.

It looks like it was stored in a barn, or maybe an old chicken house.

a glass pack is a muffler right?

Yes but with emissions you may want a muffler. I didn't think they did that in ohio. I had to look I was sure you lived in california.

Still want engine bay pics:rock_band

/hijack :10:

Where do i get a cai like that???
Did you have it made or what dude?

i wanna know how he got it so clean
but that cai looks bitchin too

Real mechanics know how to clean engine bays better than I do.

Heh, clean is just a matter of time and attention to detail.

Most of the mechanics I know drive some of the filthiest pieces of junk you've ever seen... you work on customer's cars all day and the LAST thing you want to do in your time off is work on your own.

Supramacist, I thought you'd seen my setup before? It's pretty much a customized Civic FULL CAI and my 3.5" MAF... No N/A AFM choking up my engine. ;)

I knew knew you went maf pro And I recall us talking about your bastardized cai. But, nope. Never seen it dude.

It's the same way when you're a body man or a painter. Your wheels are always half bondo and half primer.

You should do a write up on the intake man. I know the maf is somewhere between 5 and 700 bucks.

Oh, well, there you go... not bad looking for Honduh parts! :eusa_danc

It's the same way when you're a body man or a painter. Your wheels are always half bondo and half primer.

Lol, I don't know about that... well, half the time. My step-mother's cousin owns and runs a body shop (he actually work there too). Most of their guys are rollin' some sweet rides. I'm still trying to get his to give me a sweet dael on completely redoing my car's paint... but, I'm talking about a full strip and complete respray, so he's not going to just charge me cost. :(

You should do a write up on the intake man. I know the maf is somewhere between 5 and 700 bucks.

Actually, the MAF is the cheap part. ;) The supporting electronics are a bit pricey, but not that bad considering what you get out of them.

The kit I used as the base for my CAI looks like this:
http://www.fadingworld.com/Supra/MAFTwriteup/civic.jpg

I bought it off E-Bay for pretty cheap. The auction description was "96-00 Honda Civic CX/DX/LX Cold Intake System 97 98 R". You guys will need to add an adapter to the mix to adapt the stock AFM's bolt flange to a 2.75" or 3" pipe that you can connect a coupler to. Then it's just a matter of cutting everything to fit. I do recommend buying quality silicone couplers to use on the intake though. The ones that come with the kit aren't very good.

how would i go then from a 3 into to a 2.5?

Look back at his pic and pay attention this time. Then come back and tell me. You have to try dude. Just because I have been dropping dimes doesn't mean you need to roll over. Problem solve bro. It's all in the pic there are only 2 major things that you can't see. What are they?

I'm certain the piping I bought is 2.75" OD. Most Civic kits are.

If I recall correctly, the throttle body is 2.75" OD and 2.6" ID. A straight coupler may tighten down enough if you get 3" piping, but the lip as the air moves into the TB will create turbulence... not desirable, especially on a N/A. So, I would try to get something 2.75" OD and avoid the 3". The 3" ones are usually labeled as such (because alot of idiots think bigger actually is better and they sell faster if they're labeled), the 2.75" is the more common and the auctions don't always state that they're that size.

im talkin about exhaust sorry.

That looks like 3 inch. You want to reduce down to 2.5 inches.

Where would i do that at?
take it down to 2.5 out of the muffler?
otherwise i would have to buy a whole new cat-back?

2.5" the whole way is what he's referring to.

The optimum size for your car really depends on your driving style.

In the lower RPM range your engine may be having to push the exhaust out instead of the exhaust's own momentum carrying it most of the way. This'll hurt your throttle responsiveness and low end power.

However, if you're constantly driving the engine at VERY high RPMs (I'd say over 5000K) you'll gain a little bit on the top end. I really don't recommend driving like that on an old engine.

While our cars do have a displacement high enough to see a benefit from such a large diameter exhaust, they don't really rev high enough to merit the trade off. 3" is great for turbo cars as the car can clear out the exhaust faster and this allows the turbo to spool quicker.

Condensing down to 2.5" (even after only 2' of 3") isn't really going to help too much at your lower RPMs it may actually create even more resistance for the engine to overcome.

Alright. Now, we are all on the same page...., MY BAD.

k so i should try to stick with the same size, right?

You can do that and if it's not stock you may want to concider that along with all else.
