My x-pipe was installed where the front two resonators were and for better flow the shop used a step up 3" x-pipe(meaning it steps to 3" then back down to 2.25").

H-pipes generally do make deeper sound but aren't quite as good for performance, no one that I have seen has put one on a 6er.

Sounds good enough for me. I'll give this a try before I go and spend $1000+ on a Magnaflow. Any suggestions on where to get an X-Pipe? Pretty close with my mechanic so I'm sure he could help me out too.
