Re: Test Pipes
There may be a slight MPG gain but there certainly will not be a 5% HP gain. I liked the sound of no cat with a free flowing exhaust as well, but then I got tired of the gas smell and flaky O2 simulator so I had a Spintech 3" high flow cat put on...it had pretty much the same sound as without a cat. Some people do have issues with the SES and a high flow cat some don't, the best way is to have the post-cat O2 sensor related trouble codes disabled using a custom tune (like wait4me or pcmforless).
