will do skip, they are pretty cool, not as loud as I thought they would be win I first pulled thim out of the box, you can look right through thim (well the right one left has that bend), just look like a glass pack. at 55 you can hear the engine going put, put, put not patato but still pretty cool. all the noise is comming from the right side not use to that the bike was sterio now it right ear only. and you cant hear the vavles tapping you can hear ENGINE! :hat
