Rock It
I love to ride
Any slip on silencer is only going to change the noise any power increase would be so small it would make you laugh , now go with Paul's complete system(which I would recommend) then you will have a work of art and some more power.(when tuned correctly)
Yes I thought as much, but does the Rocket really need any more power? A change in sound is certainly needed I think, probably cause my last bike was a Harley before falling in love with a Rocket, which really makes a Harley look like a bicycle now to me.
