Prochambers are awesome.

Prochamber it is! I'll have one next week . No better sound than pypes mid-mufflers and prochamberI think.

All of MAC's items look sooo good too. My MAC mufflers looked so good under the car I hated to get rid of them.

So much for Rahal Jr!!

I'm going to get another dyno run of my pypes mids/OR H-Pipe this week and then one after the prochamber install. The prochamber HAS to flow better just by design.

I read that the prochamber is a combination of an H and X pipe.

That's true. The pipes enter the chamber straight through, like an H. The pipes in the rear extend about 1.5 to 2 inches into the chamber as an X design.
