1 Adam Posted April 16, 2004 Share Posted April 16, 2004 Hi, Still running my original exhaust system what was on the car when it was imported. Kinda getting bored of the sweet pur....think its time for a bit more noise and very hopefully a power increase. I got the car up on the ramps and had a look at the exhaust system. It's a trust exhaust, 4 inch stainless back box pipe but the rest of the system doesn't look special? Can i decat maybe? Any light on the subect would be cool peeps Adam Quote Link to comment Share on other sites More sharing options...
Lewis Posted April 16, 2004 Share Posted April 16, 2004 Trust are Greddy I think... http://www.batlground.com/index.php?content=catalog&category=38 -----FROM LINK------ GReddy TR Power Evolution II This is an insane full dp-back exhaust kit that utilizes 4" (!!) piping, straight through mufflers, and v-band clamps instead of the typical 2/3-bolt flanges. This special order item takes 4-6 weeks for delivery from Trust (Greddy) Japan, but for the money this is the ultimate exhaust system. This exhaust goes from the pre-cat back. So on big singles, it would go from the turbo DP back. compatible with: Supra 93-97 TT, Supra 93-97 NA Quote Link to comment Share on other sites More sharing options...
1 Adam Posted April 16, 2004 Author Share Posted April 16, 2004 Hey thanks Stealth. I wonder if it's worth decating or not?? It's very quiet at the moment plus would love a bit more power. Quote Link to comment Share on other sites More sharing options...
Lewis Posted April 16, 2004 Share Posted April 16, 2004 Decat will make it: a) louder b) less restrictive - more power I guess it depends what you want out of it. Quote Link to comment Share on other sites More sharing options...
1 Adam Posted April 16, 2004 Author Share Posted April 16, 2004 Yeh definetly BOTH! Decat pipes.....are they like a universal pipes what will fit most systems or do you think I will have to do my homework and find out what model of greddy exhaust it is and then get the pipes to fit that particular system??

Lewis Posted April 16, 2004 Share Posted April 16, 2004 Speak to chris wilson he is the decat dude Dont think exhaust make matters when it comes to the decat just decide which cat you want out (or both) and speak to chris Quote Link to comment Share on other sites More sharing options...

It's very quiet at the moment plus would love a bit more power. If you decat you'll more than likely need a restricter ring (see CW) to limit the amount of boost now that the system is that much freer flowing. Unless you can find a friendly MoT tester be prepared to have to refit the cat(s) every year to get a ticket. If all the above is OK, then go for it Personally, I can't be arsed to mess about fitting and removing the cats every year, and, realistically the number times that I really NEED that extra power over a catted system with a free flowing cat back system I can count on one FINGER If I was into track days or drag racing of course it would be a different matter. As usuall YMMV Quote Link to comment Share on other sites More sharing options...
