exhaust with a good note?
 

i'm getting a 87 NA supra and its not an aftermarket muffler, not sure which type but its one of the "fart can" ones and don't really want that. I want a nice tuner note. what kind of exhaust should I get?

there is a very good thread about this in the faq.

megan racing makes an amazing muffler, i have a 4.5 (took out the silencer) and yes it seems a little to big but idle its not that load and it sounds great reving thru any gear.

can listen to some hear

works nice if you have a sub woofer

yeah i have looked there but most of them are for turbo supras. does the pacesetter cat back sound good?

turbo or no turbo, it will still work, thay are the same from the cat back
only real options you have are pacesetter(get what you pay for), turbo exhaust, or make your own with pipe and choice of muffler

I have the hks with the dual tips which sounds really good now, should sound better with the header on once i get the top end back together

i like the HKS turbo cat back system but its like $550. I also don't mind the sound of the pacesetter cat back exhaust and the $250 price tag doesn't hurt either :)

I have a friend with the pacesetter catback on his 87 NA. It sounds decent, almost has a hybrid between tuner/exotic sound at the end of the RPMs. Not the best, but definitely not the worst.

Turbos and N/As sound COMPLETELY different.


I really liked my N/A with a 2.5" catback with no resonator and a Borla ProXS muffler. Very nice and deep, a bit of a bumble and none of that super farty $h!t all the jackasses with their 3.5" exhausts and coffee can mufflered Honda's think is so hot. Besides, too big and you'll take a performance hit. I still think I would have preferred a resonator to quiet it down further, but I went turbo before getting around to that and the turbo cut the noise down a ton.

The ideals are: as straight a run as possible (as few bends as you can manage, mandrel bends preferred), acute angles (avoid bends greater than 45 degrees like the plague), straight through resonator and muffler.

Of note too is that 7M's have a horrible drone around 2.5KRPM... a good resonator and muffler will help prevent this headache inducing nuisance.

I have the pacesetter header with a no name cat and cat back piping with a Megan Racing Muffler. Sounds nice and deep.

is it a high flow cat? and do you know what brand or size the cat back piping is?

Yeah its high flow, and the pipng is 2.5, right before the muffler I think it drops down to 2.25 inch. i was on the car when I bought it. I did put the headers on tho.

what does everyone think of the HKS cat back systems?

HKS has a nice sound, as does Blitz. The Blitz one is LOUD though. :werd:

look familiar ? https://www.t-mobilepictures.com/mya...&th=210&s=true

I told you I lived across the street from the college

so do you guys think i should put headers on my car even if its just for street use? I heard that the headers will make high RPM gain but that won't be the ideal range for street use but it would match the intake since its better for higher RPMs. but arent there headers for lower RPMs too like how long tube headers are better for low RPM's than shorties.

and with my engine stock for now, should i just leave the tube diameter alone and not bother with a cat back system? and will have to leave the CAT alone since i need emissions for 2 more years until its 25 yrs old :)

bump......

mvp motorsport offers a good header.. company took over after the last one went tails up. about 440 for 17 rwhp to an na.. least thats what their claiming.

just a quick hijack along the same topic.
Is there any downfall to running an exposed downpipe? eliminating cat back? seems a tad risky to me to just have my downpipe hanging opened like that.. might be worried about critters making their way into my turbo!

i just checked and they don't make headers for a 87 supra. do you think pacesetter's headers would net around the same hp gain?
do all of the headers available for supras focus on the upper RPM range because i know for my camaro i can get them for lower or upper RPM range( long tube vs shorties)?

and since i already have a muffler(got the car yesterday and it doesn't sound too bad, i think will keep it), do you think it would be beneficial to get 2.5" cat back tubing or just leave that alone since my engines stock except for K&N air filter and just get headers and/or high flow cats?

i wouldnt go above 2.5. I dont know about the low to high rpm.. which one is better for a na supra.. not a clue. I would probably go for the low rpm one, give me a little bit more off the line?

i don't think there would be much of a difference if i just keep the stock 2.25" pipes with the stock engine. i could maybe get a high flow cat instead though and/or headers

well headers that perform at lower RPMs would be better for street use but i saw on here that the headers are for higher RPM's. but there should be the option of both types

maybe i should just take off the exhaust that my car came with and just go back to the OEM exhaust. I'm afraid it will sound ricer with the "fart cans"

Possibly exhaust gases getting into the cabin may be an issue if any grommets/drain bungs are pushed out, other than that I'd just imagine the main problem being how to explain it to Johnny Law... Still might try it myself though since the heat shields on my system keep catching speed humps & anything slightly above completely flat!

eh no emissions here. good point about the police. can always say.. "on my way to the garage officer!" then go put it back on. lol.
exhaust gas entering the cabin is a good point. will play with it.
thanks for the info

I am the owner of the afore-mentioned supra with a pace-setter 2.5'' cat-back exhaust. The exhaust sounds nice, the only beef I had with it is fitment. I bolted it on to my car at home and then I took it to an exhaust shop and paid 30 bucks to have it altered so it wasnt touching anything and to have it welded to the cat. It is definitely not a loud note that produces, it doesn't resonate and it doesn't drone so I like it. jegs.com ( I know ) had the best price on it when I bought it.

IMHO, It is always worth while to do three things to a street car.

Exhaust/Header,Cone Filter/MAF adapter, MSD Igntion or other igntion upgrade.

Combine these three and you will have a considerbly better running and faster car and if you can keep your foot out of it, better fuel economy too.

On the note of short or long tube headers, I am pretty sure all of the headers for the mk3 are pretty close to the same length. there are no shorty headers like youd find for your camaro.

A side note: My car originally had no cat on it, i took the on off of my turbo to put on it and my car actually ran better and than not having, revved up a lot smoother under load.

if you have any further questions just let me know
