I am looking for a new can for my 2002 Mastiff (sonic, speedy and aesthetic grounds) . Many of you seem to have, and rate, M4 cans. Having a few problems sourcing those here in Englandland. Have found that the Carbon Can Company do a Mastiff specific stainless,carbon and
titanium range, and that G-force say they manufacture a can, although I don't see any stockists. Any recommendations, or is it just a length of plumbing pipe with some advertising? Does anything out there make much of a difference?
