I always wondered if the material for the pipe had any advantages and disadvantages. I know that most manufacturers try to increase performance by studying the resonant characteristics of the Pipes shape. The Divergent and convergent cones theory, which aid in scavenging by pushing the fuel back into the engine with exhaust back pressure. So would it make a difference what the pipe was made outta of? I would think probably less than it's shape.
