Hi quick question from a newbie, I hsve a 98 z with an ls1 that has an aftermarket exhaust, I'm wanting to add tsp long tube headers to my setup, can I buy just the headers and they'll hook up to my current plumbing under there or do I need to also order the catted y pipe? Thanks in advance. Learning in progress
