Everyone should see this coming. We'll all be riding less aggressive sounding bikes soon enough. My biggest beef is with the $$$. What about those of us that shelled out $400-600 for pipes, not the rules change, and were going to have to shell out another $400 -600 (yea right- when they get you over a barrel the price triples). This is BR bovine recycling and needs to have a grandfather clause. Hope you didn't throw your AI's away!!!!
