Hey guys I'm installing my new Mac axleback system this week. Now I'm thinking of getting a Mac prochamber. Does anyone have any experience with them? Do they help sound or performance? are they expensive? Thanks

 

my brother has one on his 03 GT, sound is amazing. performance was a little better. ill see if i can get a video clip or some more info.

 

a video would awesome. thanks man [sm=shades.gif]
