A prochamber is a mid-pipe. It is supposed to be a little deeper but at a little quieter than the H pipe. There a few variations of the prochamber, O/R which is no cats and splice which would fit into the stock cats. Opinions vary as far was what sounds good. Any o/r pipe with loudmouths would not sound good. Bassanis sound good with almost any midpipe. I would get both an o/r prochamber and slps. I wouldn't use them together but then you could switch exhaust set-ups from time to time; bassani and o/r prochamber and stock h with slps.

Hey I'm getting ready to maybe pull the plug on the prochamber that is used with stock cats. I have Mac Axlebacks , what do you think that would sound like? I want some more raspy sound but maybe a little quieter than the H-pipe that sounds like what I need./ Answer back please.

Not really sure what it sound like. I have read that prochambers that connect to the stock cats sound a little quieter yet deeper. When I had I using an O/R prochamber with my magnapacks, it was deep, loud, and had a raspy sound to it. Although I would describe the sound as being raspy, it was not tinny. Adding hi-flow cats improved the sound overall.
