My passenger side exhaust manifold warped and snapped off the rear two bolts. I was lucky in that all my studs came out and even the broken ones. I have gotten stainless studs and nuts to replace them.
I now need to get a new exhaust manifold and was wondering opinions on aftermarket vs OEM.

I have priced the OEM at around 120 but know its a exact fit and size.
Dorman I can get for about 60.00
AJ Manifolds for about 75.00
1A Auto for about 70.00

Curious about the longevity of these others vs OEM for the price. OEMs gave me 14 years before it died. Never had to replace these and really dont want to go long tubes at this time either.


Whats the best way to clean the mating surface on the alum head side as I know scrapers and some cleaning pads will scratch them up.
