im about to order some mac long tube headers and was wondering what else do i need to get? i know i need the o2 extension but do i need gaskets or anything?
thanks

 

i think mac comes with gaskets although dont quote me on that.

 

You dont wanna use the gaskets they send you. Pick up a pair of Fel-Pro gaskets, some Copper Sealer and some Stage 8 Locking Header Bolts. Youll be very happy that you did. The gaskets and copper seal will keep you from leaking and the locking bolts will make sure your headers dont vibrate loose.

 

did you get an shorter mid pipe for that.

 

i used the sopper gaskets they sent me with my headers and they leaked like crazy and i got myself a set of fel pro gaskets and do leaks and sounds great
