I was riding at Hollister SVRA last weekend and saw a 426 with what looked like a dual exhaust headpipe like a honda xr400. It was literally 2 pipes, then they went into the silencer. It looked like a big gun tailpipe but had no logo or sticker. The whole camp saw it so i'm not going crazy. My friend works at a honda/yamaha parts department and never saw one before. Does anyone run such a pipe or heard of one? We only saw him one time going down the main road and he had his little boy riding behind so we got a long look at it but never saw him again. I really did see it and no I don't see ufo's off the back porch of my mobile.
