MAC Prochamber?
 

I just installed a Mac 2.5" cat-back system on my 2000 GT. It sounds great! I am thinking about adding a Mac prochamber to go along with it. My question is what are the pros & cons of the prochamber? Also. how will it affect the sound/performance of the car?

yeah the Mac sure sounds cool : ) i love mine actually i have a question for you have you noticed it banging on the floor boards at all when going over small bumps? mine does all the time and ill be damned if i can find where it is hitting of even why its hitting looks to me like it has plenty of room to move without touching :confused:

I have not had any problems with it hitting anything. Maybe you need to adjust the exhaust hangers. They are rubber and can move around a little bit. I doubt that would cause it to hit anything though. Have you called Mac's support line?
