GT inspired Exaust tone.
 

Morning,
Let me get the important stuff out of the way. I live in NM and have no Inspections or Sniff test to pass. Thats said I was wondering if I could get a few suggestions for a new exhaust setup. Right now I just running the following

3" Downpipe
3" pipe
Racing Beat Y
Magnaflow Domestic Fartcans.

This was done by the previous owner. I, on the other hand, am looking for a FIA GTesq Inspired sound. Something that will produce a high pitched scream and WOT. Similar to a F1 car. The REVII system is mellow which is nice for city cruising but I’m looking for aggressiveness without getting the Tinny noise I have now. The only restriction I have is the dB requirement for race tracks. I have been told that Single tip N1s are the way to go but lets face it. 3rd gear deceleration flames look much better out of two tips… :naughty:

P.S.
I did view a few Youtube vids but I value the comentariats opinion.

I love my HKS silent high power single exhaust and have heard good things about the Apexi N1 system. And if you want duals I think you can get both systems dual. That way you can get a more aggressive sound without being too ricey

Rotaries always had their own distinct sound. not sure how that could sound like a GT car

Isn't a dual exhaust rice because it's purely for looks?!

Try a system with a resonator and or a high flow cat as it might get rid of the tinny sound.?

Dual exhaust helps tone too. Not just looks.

I run a 3" magnaflow high flow cat, two summit 2.5" glasspacks (one per side) and finish with two 2.5" magnaflow stainless mufflers. On my T2, at high revs, it does sound quite a bit like formula cars IMHO. About as close as you could I suppose.. as we are talking about two completely different engines(pistons vs rotors, and much higher revs on F1)... And at lower RPMs, its very growly. I wouldn't have it any other way. Love it.

I have the dual apexi n1 on my 10th ae and it sounds real nice and deep even higher rpms. Btw running stock dp and straight pipe all the way Back.

Glass pack mufflers before the end of the car(tail) will Melt.So no sense in trying to use one for a Presilencer.
I'd go with something along the Lines of HKS,Apexi or try Borla XR1(?).
If you don't care about Weight then Racing Beat makes the REVII system,and it is Durable as hell,but it weighs in over 80 pounds complete.(2 mufflers,y pipe,.Presilencer,and down pipe)Get the 3 inch version.

I'm going to run a presilencer 40" back from my turbo then straight pipe the rest with 3" on my the track car i'll have a video up as soon as i'm done.

Add two more rotors to your car, done.

:icon_no2:

Anyway to the OP:

If your engine still has a stock port and is a 13B, you will not be getting the F1 sound, no matter how hard you try. That sound comes with an agressive port or 3 rotor engine. Working with the exhaust will only lead to a nicer 2 rotor tone.

some of the JDM systems, like the re amemyia or the knightsports are the closest i've heard to an "F1" sound, although its still pretty far away. they are higher pitched than what we are used too

we got to see the 2007 Ferrari F1 car run at laguna seca, and that did NOT sound like anything ive ever heard before... its a lot different in person than on TV too. when its coming at you, all you hear is a big sucking noise, then it passes with the shriek, which is probably the trans. after it passes you you can hear like a drumming noise, and the shifts sound like a rifle.

it had everyone, even the trophy wives, stop and watch.

oh AND its faster coming out of the corners than most cars will be at the end of the straight, its pretty nuts. they were 2 seconds off the overall track record.

i thought the majority of the F1 sound comes from the motor doing about, umm lets say 19000rpm?!?!?!?!

here's a perfect example of the difference rpm makes to the sound

Ummm.... Yeah... that there is a 20b with an aggresive port, just like I was saying. You will never get that sound out of a 13b. Plus that is not 19,00rpm or anywhere near it.

Noone said it was 19K, he was refering to F1 cars that depending on year do 18K to 23K.

Riz.

this. first car sounds like a turbo 13b, second car is N/A 20b at 10k rpm, and the difference of sounds it staggering. obviously the second car, the fc does not sound exactly like an F1 car, but it's a lot closer then the 13b turbo.

thus the F1 sounds comes from the engine, not the exhaust.

back in the day i had a link to a turbo 20B doing 14k rpm on a dyno, can't find it now.

This?

Not 14k but I can't find the video with it going there.

Melted or not, sounds great.

wow.

only if you don't like everyone near your car.


same car, still looking for the 14k video. but still 0-100mph in 4 seconds?

yup.

3-rotor peripheral ported engine + Racing Beat "Rotor" muffler = win!

Your car will never sound anything close to that. However, you may like the sound of single or dual Apexi N1's on your car. Just make sure you get some high-quality mufflers. Cheapie mufflers sound tinny.

I agree with the others that without crazy porting and 10k+ RPM its just not going to happen but mainly since exotic rotary F1 sounds were being posted it's a must to have a good 787B in here.
