3 inch exhaust

ive looked just about everywhere and cannot find anyone who carries a full 3 inch catback exhaust for a 92 lude sir with a h22a in it. does anyone know who sells them or at least sells a full 2.5 inch catback exhaust. thanks for the help

almost all aftermarket exhausts are at least 2.5 inches, and many are 3 inches, as far as I know. Apexi N1 supposedly provides the most gains on the prelude, so look into that, as long as you don't mind the noise.

no every exhaust that i have looked at are either 60-70mm which is to small because it would be 2.25 inches in some places or just 60mm. also if they are 2.5 all the way through they dont work for my year. also the apexi which you suggested does not work for preludes. i already looked at all the known places like hks, apexi, thermal r&d, greddy, etc.

kteller sells 3inch exhasut pipes, you just have to put it all together. Go to www.preludepower.com and search in the gth gne section bcuz I think it was recently discussed.

Pacesetter MONZA is a 2.5" catback and its pretty inexpensive too...

on a side note, I was reading in Sport Compact Mag. that after 2.5" you loose some low end torque because of the very low back pressure. they had more gains with a 2.25" than the 3" or 2.5", unless you go FI. however, it was the 2.0si that they were refering to in that article...so is this true or what?

yes that is true the b series motors shouldnt use higher than a 2.25in exhaust and the h series shouldnt use higher than a 2.5in exhaust but that is for a NA vehicle im using a turbo which shouldnt use anything smaller than a 2.5. thanks for the links.

im looking at kteller and their stuff is great especially the fact that they also have a 3inch down pipe. but the one thing i notice is when i open the page or go to check out i get a warning that the site is not private or secure meaning people can see things like my cc number. is this site a good site and am i truly going to get my stuff i order.

*sigh* backpressure does not decrease torque.... back pressure is ALWAYS bad. It is misaligned exhaust pulses that lose the low end torque because the piping is too large for the lower end pulses to "suck" each other out so instead they linger around and are sucked back into the compression chamber diluting the fresh air. Too large is just as bad as too small.
