I got sick of the sewing machine sound of the thou, so I got a new Scorpion slip-on for the bike. The muffler and joiner pipe are seperate pieces, making it easier to get the right position under the tail of the bike. Sounds NAAAASTY!, now!...and only cost me $355 new. :grin: It's a nicely made set up from a UK company that is well known in Europe, but not so much here. Worth a look.
