Does a prochamber add the same performance as an X-pipe?? i like the sound of the prochamber on magnapacks but i also want the performance.

I was going to buy the prochamber, but after I drove a stang with a Bassani X I was sold on the Bassani. Did you go to mustangexhaust.com to listen to the diffrent setups?
