If you buy one make sure all you exhaust hangers are doing thier jobs, especially at the downpipe. Alot of people dont have thier DP's supported, or are too low and bang it causing the manifold to crack. Also I heard splitting the runners is a good idea. But honestly, a bored out log mani with EWG>tubular, I know quite a few people making around and over 400whp with that setup, and spool is retarded fast.
