Who Does A High Flow Exhaust In 4 Inch Or 90mm

[BU5TER]

Hi guys and girls thinking about exhausts lately and decided I may need a higher flowing exhaust any ideas or suggestions would be great

prefer at this point not to get get a off the shelf Jap 90mm as its a bit out of my budget, 2nd hand jap would be fine but maybe hard to find?

Brett, an off the shelf jap system will probably be cheaper than a custom made one. Trust do one (TR) from memory, but it's super duper loud (but you wouldn't care about that ). It's only mild steel so not too exxy.

hahaha thanks Mik

hahaha thanks Mik

TRUST do an RO...standing for Race Only...its what Stacey's grocery getter has on it....it even has a little section that you can pop out and fit a cat if you please.

Check PM.

Maybe look at a Apexi N1 dual system.

most jap catbacks are 80mm or 95mm

[TTT]

Cat back my dump pipe is fine hahaha that sounds so wrong

With exhausts will say a twin 2 1/2" exhaust flow more then a 4" to me it should as you've got 5" of exhaust flow but Im probably wrong hahaha

[R31Nismoid]

i think 2 3/4... to 3" twin would work

quiet too

[KamikazeR33]

should measure nicely on the richter scale

The Trust TR is a 3.75" - and is WAY loud... had one on my 33GTSt and now on the 32GTR.

The pipe is big...

[BU5TER]

mate whats it like with the silencer in

[R31Nismoid]

Mm... you car is one of the loudest ive ever heard marcus

i can vouch for noise factor

[Ronin 09]

mate whats it like with the silencer in

brett, without on the GTSt it did 109dB

with it in it knocks off a HEAP of dB - I reckon it's around 96dB with it in.

it drones a bit on the freeway without the silencer, but with the silencer in the exhaust is very streetable.

ive got the twin 2.5" system after the cat, back to 2x 3" mufflers. It runs no cat, just a 3" front.

Its a damn quiet system, and doesnt drone (made out of ms, as well as splitting it helps)

2x2.5" pipes equal about the same area as a single 3 3/4" pipe.

It fixed up my flow dramas behind the rb30det. Even Cubes says its a damn quiet exhaust for what it is.

are there any centre muffles/resonators in that system marcus, or just the rear can?

[raz0r$harP.UK]

HKS have some nutter exhausts.. my brother has an old Hi-Power (?) one on his 32 that is 3.5" straight through to a 6" cannon.

These days their Titanium Racing Muffler uses 102mm diameter piping

[TTT]

Brett... I've got cat back piping with center muffler in 3.5" with a crushed muffler I've been trying to sell.

it has a few dents in it but if it will help you out, you can have it.

Your wrong at a guestimate, twin 2.5 inch is about the same flow as a single 3.5 inch pipe. (I could work it out, but too busy) It's all about the surface area. Think about how many 2.5 inch pipes you could fit inside a 5 inch pipe.

That TR is the one I was talking about...very loud though.
