I got a set of B&E proformance pipes and I will agree that the 07 pipe will not work since they are not the same. you could buy a set of 06 pipe and recore them but they don't sount much better then the 07 stock pipe. I did the fullsac true dual convet and B&E pipes. and I'm not sold on the results yet. I will give it a month of so and if I'm not happy I'll return my bike back to stock.
