I regret not shaving some of the casting off near the front bolts before getting mine coated. Because I cant get a socket onto those. Have to use a wrench but the rad is right there... Will prob have to make some shorter socket or something.

how long ago did you buy your manifold? Has this been corrected on their casting mold?

I didn't back to back test it but its designed to be slightly larger then stock and it makes power. Even unported , I'm sure it played a role in the power I've made .
It also is less prone to cracking then a tubular manifold and preserves the cars sound. I think its a great choice for stock frame cars.

The Arps snap. Never had an OEM break. Dsm forums cry about it too I guess.
@ForcedPerformance with such a nice manifold I would of made nice fasteners like I made from oem

The ARPs are likely super strong in tension but because they are a hard steel, when locked up in the exhaust mani, they fail in rotation?
