I am installing a SE stage 2 (103ci +se255 cam) on my 2009 Cross Bones, and then I would like also to change from my SE mufflers to 2to1 exhaust pipes, from experiences what should be the best (torque gain but not too noisy because in Europe its getting taff (toward police) to ride too noisy bike) : D&D Low Cat and V&H Pro Pipe Hi-output (I know there are many others but at the end I selected these ones)

Thanks
