tuned pipe
I have bought a tuned pipe for a .21 os max.. I have cut and rewelded the manifold so the exhaust goes out the cowling on my Pay n Pak hydro, so now I cannot change the length of it. need to shorten the pipe up for high speed performance. Can I cut some length off the front of the pipe? Seems to be plenty there. Can someboly explain to me why not? Thanks for any help.
