If you read my previous post about the Thunder Alley Exhaust, you heard me whinning about how loud it is. Even w/ the SA. In my quest to reduce the noise, I took a SS scouring pad, cut in half and placed it inside the perforated 1 1/2" pipe in front of the diffuser. Most of the exhaust flow must pass through the pad and the results were very good. Got 2 hours riding today and the performance is still there. Its just a bit quieter w/ the same big exhaust tone. The question is. has anyone had experience using SS wool like this in an exhaust application. Will it last or eventually burn up.
