Finally a high performance end cap for the European and Australian spec bikes. The stock muffler is great on the inside but the stock end cap has a restirctive 25mm ID outlet. This cap is lighter than the stock one and opens up the outlet size to 36mm. A definite increase in power from bottom to top. No reason anymore to spend a lot of money on an aftermarket muffler. Requires no addition tuning
