Xanth Posted August 4, 2005 Share Posted August 4, 2005 The downpipe is 2.5", it then goes into the resonator and changes inside the resonator to 2", then it splits at the y-pipe to 1.5" I know, why right... Link to comment Share on other sites More sharing options...

For better low end and response. Link to comment Share on other sites More sharing options...
starlabs Posted August 4, 2005 Share Posted August 4, 2005 It's not a perfect circle... it's an oval. So it's slightly wider than tall, I believe. -=- Livin life at 140 BPM -=- Link to comment Share on other sites More sharing options...
edmundu Posted August 9, 2005 Share Posted August 9, 2005 The downpipe is 2.5", it then goes into the resonator and changes inside the resonator to 2", then it splits at the y-pipe to 1.5" I know, why right... According to what source? I measured mine, and it is a consistent 62mm or 2.44 inches, and at the y pipe 48mm or 1.89 inches on each leg. Are you quoting inside diameters? All my measurements are of course outside diameter. Link to comment Share on other sites More sharing options...
fragment Posted August 10, 2005 Share Posted August 10, 2005 For better low end and response. Um, no. The turbo provides more than enough backpressure for the engine. Any restriction after the turbo only hurts performance, everywhere in the powerband. Link to comment Share on other sites More sharing options...
