Just a heads up. If anyone is thinking of a new end can you can get 10% off by using the code BEOSHOW at the checkout or over the phone. I recently replaced my silencer on my bike and it no longer sound like a sewing machine 
Great!
Had a Beowulf on my old CBR600f and it sounded awesome!
Yeah am pleased with it too. The baffle is pretty minimal and sounds good even with it in though it is under my seat at the moment as I found that unbaffled the bike is pulling a bit better at the higher rev range.
