Scottrw Posted May 26, 2005 Share Posted May 26, 2005 Hello all.... I have done a little searching & it seems that the only really benefit to be gained from a n/a car come from straight through exhaust & filter!! Am I right? I believe there are two cats thus making the standard exhaust quite restrictive right? So what system should I be looking at to get best power gains!? Although I want a system that sounds nice, I dont want it to be too loud from inside the car as I wanna be able to hear my tunes & not get brain ache on motorway journeys! Any help & recommendations would be gratefully recieved!! Link to comment Share on other sites More sharing options...
Jake Posted May 26, 2005 Share Posted May 26, 2005 The aftermarket air filter is only good for making the car sound faster, it actually decreases power a little. Yes, two cats as standard. Decatted NA Supras with a straight through exhaust are incredibly loud, much more so than a deatted TT. Link to comment Share on other sites More sharing options...

Pete Posted May 26, 2005 Share Posted May 26, 2005 Mine isn't THAT loud. Depends what your back box is like. Link to comment Share on other sites More sharing options...
Stonkin Posted May 26, 2005 Share Posted May 26, 2005 Is there such a thing as buying a centre de-cat that has a resonator built in, i only ask cos with the scooby, you could buy the centre de-cats with and without to reduce any 'booming' when cruising on the motorway (or at speeds with similar revs). Either one gave the same eperformance increase. Just curious... Link to comment Share on other sites More sharing options...

Pete Posted May 26, 2005 Share Posted May 26, 2005 No idea what it is - can't see anything on it to indicate. The noise level is just right though. Link to comment Share on other sites More sharing options...
Steve W2 Posted May 26, 2005 Share Posted May 26, 2005 Mine is You got an RSR? My RSR is very annoyingly loud when cruising anywhere between 50-90MPH. Does sound ace though. Just really boomy on the motorway. Even with the baffle in. Link to comment Share on other sites More sharing options...
Scottrw Posted May 26, 2005 Author Share Posted May 26, 2005 Well I dont really want it that loud it would annoy me,....... So Im guessing there is no way around it then!?? If you want an unresticted Exhaust then its noisy all the way!?? Otherwise a standard exhaust which is restrictive!?? Arggh! Link to comment Share on other sites More sharing options...

You could leave the second cat in, this will help deaden the noise a little. Or get a custom decat pipe made with a silencer in place of the 2nd cat.

Whitesupraboy2 Posted May 26, 2005 Share Posted May 26, 2005 or remove both cats for performance but leave standard Back box. that will be nice and quiet and give a bit of performance increase Link to comment Share on other sites More sharing options...
Bobbystone Posted May 26, 2005 Share Posted May 26, 2005 ive had both cats done with an Apexi N1 zaust and sounds awsome but only @ full throttle but quiet for normal and motorway driving. looks good too:) Whifbitz done mine in Enfield Link to comment Share on other sites More sharing options...
