I know this has been asked a 1000 times...but can someone tell me what part of the exhaust is the "take-off'? Will a GT take off work on a V6?And one other thing...I have an exhaust leak,was thinking of going with headers...does anyone have suggestions to this? I am running a pure stock engine w/ K & N filter...no other mods in the engine compartment....or should I just stick with the stock manifold?
