An aftermarket pipe WILL HELP the problem, but not entirely eliminate it. The stock pipe is double wall, and holds heat, which adds to the problem, where the aftermarket pipes dissapate heat MUCH better, HELPING to alleviate the problem. I have several friends that ride 220's here in Idaho, and they have been working through that problem. I didn't get mine until it was cooler, and I put a P.C. pipe on it, so I haven't experienced it yet. Probably will to some degree this summer, though.
