I don't know Subaru as well as you, but if you want high hp don't you want to use a equal length header instead of the UEL header? So basically UEL is a poor choice for high horsepower? I remember reading that in an article. Also something about UEL screwing up cylinder 2 and 4 and causing a failure? So is the only reason for UEL for that deep rumble? Any other benefit?
