Well I just received my Titanium Mid length headers,3" h-pipe with cats and 3" catback from JBA.I am still trying trying to decide which gaskets to use. Jba says to use theirs but I have did some research about using the oe gaskets. My car only has 800 miles on it should I still buy new oe gaskets if I decide to go that way? Any tips on installing? Is it best to drop the kmember or just jack up the motor? Am I going to need 02 extensions? Any advice would be great!
