Exhaust and tunning

[Qckslvr]

I too have had varying success with headers. Hooker headers for a 390 that took 2 hours of grinding, heat, and massaging to make fit a Mustang. Or OBX turbo header that crack midway through a race on a Miata.

So yes I am skeptical.

I live in CA, home of the smog demons CARB.

I am not opposed to changing the system back to stock every two years. So the tip on changing the bolts to studs, is greatly appreciated. I shall check into ARP.

I am looking for improved performance, and saving my very expensive cats from future replacement.

Oh, don't get me started on aftermarket header fitment issues! Seems like we've both been there many times before!

ARP studs? Should not need to go to all that much trouble. You do not need super strength steel studs as you are threading into an aluminum head, and those threads are the weakest link. Simply go to your local Lowe's Depot and buy a dozen M6 bolts in the longest thread length that they have, and then Dremel off the heads. Voila: Studs!
