i've decided to go with the LMII's and now i need to know if i should go with a BBK catted H, or the catted Prochamber? i was about to order the H when i read something about the prochamber giving a better deeper rumble. anyone got sound clips of LMII's and a prochamber? i dont' know much about the prochamber at all. what is that little box thing? is it closer to an X than an H?

 

I have prochamber on my car, and my buddy has a H, hes is louder and lower rpm and my is louder in the upper rpm.....

 

are both of yours catted? anyone else have any input on which way to go?

 

I have the catted ProChamber with a Magnaflow catback system. Its definitely quite (though louder than stock) unless you go WOT. Also, its probably my lack of mechanic skills, but I have been having exhaust leak issues ever sine I installed the Prohamber.

 

I have a Pro-chamber on my car with my Magnaflow cat-back and have not had any problems with leaks. I also have a O/R one and really love the way that it sounds with the mangnaflow's.

 

Mine are catless...

 

I just put a catless pro chamber on my car the other day. I also have an American Thunder catback. Going from a stock H with 6 cats to a Pro Chamber with none is a HUGE difference.
