I was thinking of getting some test pipes and I just wanted to know if anyone had any problems with them. Such as warning lights, and how to fix the problem. Or would it be better to just get hi flow cats.

 

The CEL light from test pipes can be easily taken care of with a pair of non foulers. Check out this link for a DIY. http://forums.generationdub.com/view...7c1f5a5c29e68c

 

If you have an 05' you will get a CEL for sure.. but like cyphr said it's an easy fix..

do a few searches tho before you buy them.. they don't exactly sound "nice" ....

 

I have the Labree test pipes with resonator and very little rasp you can barely here it over the exhaust note (Borla TD) between 1100rpm and 2200rpm. I did a lot of research and it seemed these were the pipes people were happy with the most. Also nice pull after 3000rpms. I have an '03 so no CEL.
