not a x, not a h, but a prochamber
Are you kidding!? They're anything but quiet. I have Bassani catted X with Borla Stingers. Very loud IMO. Sounded as loud as a friend's 03 with UPR off road X and Borla Stingers.The bassani x seems a little quieter than other catted x pipes. .
I like the sound of the Borla w/ Stock H-pipe the best (deeper sound)
I just added the Magnaflow Catted X to my Borla Stinger and makes the pitch higher and you get the wide-open clatter sound once-in-a-while like those getto pickup truck exhausts. Not to mention the horrible mind numbing resonance at just over 2K.
