i've been going through old threads and looking at(rather listening to) sound clips, but can't find this combonation....i'm still trying to decided between catted x-pipe or catted pro-chamber.... i have gibson axle back and they sound good but i want louder....i have found a few clips with catted x-pipes but not catted pro-chamber...i'm trying to stay catted because they are trying to pass a smog inspection law and want to stay legal.....any help would be appreciated.....
