Exhaust Question
 

I have a '02 GT and have an exhaust dilemma. I have 2 X-pipes, one is for long-tube headers and the other is for regular headers. The x-pipe for the long-tube headers are Dr. Gas (name brand) while the other x-pipe is a generic brand (YoDude Performance).

My questions are the following:

1) What route should I take; invest in some long-tube headers and use the Dr. Gas X-pipe (which is catless) or just install the regular X-pipe?

2) What route will give me the better performance gain and why?

Thanks,
Mike
