[QUOTE=Ashikabi;3153134]Alright, goodish news on headers. JBA headers for the 04-06 GTO fit... Mostly. Physically mount just fine. There is spark plug interference on the passenger side. Also, the flanges kinda point towards the subframe. I think there is enough clearance for the exhaust guy to make it work. You have about 4 inches linear distance between the flange and the subframe to make something happen. Should be fine
Can't wait to see the end product!!!!
