Following up on some discussion from a month ago, a local did some back-to-back testing with the ARH mid-length catted headers at the same shop/dyno I used for my ported/coated exhaust manifold testing.
My results were +11whp/+8wtq
His results were +11whp/+14wtq
Conclusion:
I'll be sticking with my ported/coated manifolds and stock primary cats, especially considering they're 1/4th the cost and OEM in appearance for warranty reasons! Both setups will pass OBDII emissions inspection, and both are safe with the stock tune.
