I'm going to be dropping my new 350 in a 84 Firebird, i want to install headers on the engine but will my stock exhaust match up to the headers? I'm going to upgrade the exhaust later. Also what headers do you reccomend? Thanks

Question #1 - No.

Question #2 - Hooker 2055HKR.

Your stock y-pipe will not match up to any set of headers. However, you can buy header kits that come with a new y-pipe that will mate to your stock cat. But....You really will want to upgrade to a full 3" TPI system to rid your car of the junk stock exhaust. Your best bet is to replace the whole system.

As for recomendation, see above post by Five
