Just wondering if anyone has seen or heard, or even heard of anyone putting GP pipes on a v-twin Superbike? I have a '98 TLR with a M4 full system, a great system, but I would like to clean things up a bit and GP pipes would do it. I have ran it a little with no cans on it and it is not overly loud, just too raspy. A set of M4 GP pipes with resonators might clean that up.
Any thoughts on this?
