I pulled the muffler off my 300 last night, just to see how loud it was for myself.... definitely too loud to ride. I inspected the factory muffler and it appears to have catalytic material inside at the slip on end. I know the 500 has a cat, clearly identifiable in pictures, not so with the 300. Can anyone confirm the cat is part of the muffler on the 300, and has anyone taken the leap of removing the cat material, any potential I'll effects? I know I've done it on cars but this different.
