+1 on the Beowulf muffler
Just got mine and it's the best deal I could ever imagine on an aftermarket exhaust. Looks great, sounds great, has a lifetime warranty, and costs 1/3 to 1/2 of most anything else I've looked at. It actually got to me in North Carolina 3 business days from when they shipped it from the U.K. and cost a total inc. shipping of US$280.00! What's not to like?
