Anyone running a Catted MAC ProChamber? I am thinking of getting one instead of a catted X or H pipe but not sure on the gains or if they are any good or not good???

MAC claims 27 hp across the powerband on a Mustang GT. The Pro Chamber would be used along with my SLP cat back that is on the Mach now.

Any comments are apprecated.

 

I think it would sound a bit loud with the slp cat back,but then again i could be wrong .

 

It is catted so I am not sure how loud it would make it? I thinkI have narrowed it down to the catted ProChamber or the catted SLP X pipe. the SLP will be really loud I think compared to the MAC.
