im not positive but im pretty sure you can use stock or aftermarket headers, im not sure if they make a prochamber for lt's or not...yes they do make x pipes and h pipes for lt's...i see from you sig youve got the flows cb, i would go against the pro chamber unless you were to get macs cb. in case your wondering macs pro and catback sounds bad ass when coupled but one w/o the other is nothing to brag about. ive got an o/r x and flows catback and i personally love it. flows w/ an x is a little more raspy sounding than the hpipe.
