I'd suggest you just buy a higher quality set of headers for about the same price..those manifolds take up more room than you think. You'll have a REALLY sharp bend in the pipe to get around the cross member. From what I've seen, engines with rams horn manifolds like those don't perform as well as a GOOD set of headers. Ceramic coated, especially ceramic coated stainless, wont rust, and if they're a good set, they don't have any clearance issues.
