Newbie to mechanics, what exhaust ?

[DJ_L3ThAL]

i got a 95 R33 GTST, and i hav e been told first thing to do to a stock car when doing it up is the exhaust, its always a starting ppoint, so what exhaust should i get, ev eryone has said 3" madrel bent cat back, but whats all the 'dump pipes' and stuff about ? i want the BEST performance and i dont want it loud, i only just wanna hear it from the cabin, but outside the car it sounds just nice, im sick of my 'hey look at me' exhaust on my last car which probably decreased performance LOL!

Dump pipe runs from the turbo to the front pipe, which connects to the cat, then back through a muffler and back to the rear muffler.

The whole system is pretty restictive. By going a 3" system, you will unleash a very noticable gain in hp. Any restriction on the exhaust side will cost you hp, but if you want a quiet system, it may be a 'bit' difficult without compromising a few hp.

I have a N1 style system, which doesnt have a muffler, only a resonator on the back, so its a bit loud - I would not recommend an N1 style system if you want quiet, but there are systems out there that are quieter and flow well. It may even be worthwhile looking at going to a 4" system, to offset the restriction required by mufflers to bring the noise down - jsut make sure the internal workings of the muffler are also 4" otherwise it would be somewhat a waste of time

Sorry I couldn't be of more help

I currently have a 3" Nismo Cat Back system installed. This coming Wednesday im getting a 3" Front Pipe + Dump Pipe + 3" Cat installed.

I'll post my dyno results (before/after) next sunday so you can see the difference.

ok sweet, i saw a supra today with i think it was at least 5" maybe 6" tip, ****ing looked awesome, i want something massive on my car, does the tip matter ? can i get any tip i want or does it matter performance wise ?

[RAIDER]

get a dump pipe

u will notice the difference

mufflers pretty much mean shit nothing, it is all in the pipes off the turbo and the mandrel bend

also stainlkess steel over mild steel is the way to go

My R33 came fitted with a Kakimoto R 3" stainless system, which uses conventional (oval shaped) cans. The first thing that struck me when I test drove the car was how remarkably quiet it was - very stealthy in traffic, noone hears you coming but it flows very freely. My other car's exhaust has a nasty resonance at 2000-2150 RPM so I know where you're coming from.
