Yes Blackhog, there is no baffle for the pro pipe. But there is a mod you can do yourself that will help. It was posted by another member earlier this year in reply to a question I posed for a friend about one. His answer was to remove the rear end piece and put a hose clamp around the front set of holes on the inner pipe and to wrap the rest of it with stainless steel wool held in place with wire. It helped quiet his pipe without being too quiet. It also helped the torque a little. Dan
