X pipe question

eunosracr · 10-08-2009, 04:58 PM

Who makes an X pipe for our cars that will fit stock or aftermarket mufflers?

Also, who makes secondary cate delete pipes? I think the SS ones need to be used in conjunction with the SS headers correct?

yes. I had it installed on mine before I got new headers and it fits fine with stock headers.

yes this is not problem. I know people who used the xpipe icw ein Eisenmann exhaust as well, but here you have to do some welding.

Does it make any power?? any dyno plots??replacing the X Pipe and the Cat delete pipes?? Seems like exhaust is only benefical for weight.. except the RPi race which is quite loud....

I believe I saw dynos done by Supersprint testing out the various parts of their exhaust system, and it was ~7hp from the X-Pipe, more than I expected.

+1, am leaning towards more decibels so Xpipe would be a perfect! as long as i dont loose any hp/tq (even is ok) i'll jump on this...
