H-Pipe,X-Pipe, or ProChamber
 

On a car with long tube headers and cat back exhaust is there a better choice between these pieces. Is there enough difference between them to warrent the difference in price or is it just better to save the money and go with the H-pipe.

The Pro Chamber is supposed to be the best flowing pipe out there I think. Either way, I love my Pro Chamber. It isn't too loud and the sound is really nice. I've made a few posts on here with sound clips. Do a search for MAC in the last 30 days and you should find it.
