West 50 pipe on a 46
Hi SJN,
Looks cool but I don't know if you would get too much more power. My understanding of the pipes is that the reasonance chambers are spaced according to the engine to produce an exhaust extracting effect that will compliment the engines power band. But then again, who knows! it could be an absolute winner by fault of design... give it a go and let us know.
It would bring your engine up to max revs in a dive though so watch that you don't throw a rod at vertical (down).
