size & "H-pipe"

I am not trying to argue with OMM but my TTI step into 3" collectors, Jegs or Summit (cannot remember) X pipe kit, 3" x 8" cherrybombs before flowmaster 40's into dumps at the axle picked up ET and speed over open collectors and to me sound perfect. 3" all the way.

Some motors do need more back pressure. Some don't. I feel My car runs better with the exhaust on, Then with it just open headers. An X pipe has to be more restrictive. Your motor needs a smaller exhaust. Mine likes a big exhaust.. If I could get a 6 inch pipe under my car I might need an X pipe too.
