Vibrant was my first choice, but then I read about flex pipes breaking and having to upgrade motor mounts. Didn't want to go through all that trouble. And I read some good info about megan+RT hfc. So do you know if I can run stage 2 on FP with this instead of a true raceheader?Why megan? you won't gain much on this setup and the sound of a downpipe is not as good as a race header. If you want a cat, get the vibrant with hfc. Megan gain's like 5whp........
