I just installed a Yoshi TRC Carbon Slip-On for my K6 GSX-R600 and if you're planning on doing the same, here are some notes:
1) The Slip-on I installed was 1104272 and here are the installation instructions:

2) The instructions have 3 parts denoted by ** that you just have to figure out where they go (not explained). Parts list:
3) The muffler clamp heat insulator is obvious and goes on illustration A (below). The 2 rubber grommets need to go on illustration B & C (below). The 2 aluminum inserts are NOT the same. The small one goes in the B grommet and the bigger (hat shaped one) goes on the C grommet.
4) The instructions will lead you to believe that the Tailpipe #1 weld bracket goes behind the Oval Muffler weld bracket (reference D & E below). But the Tailpipe #1 weld bracket goes in front of the Oval Muffler weld bracket (and the grommet insert faces away from the bike).
5) The flanged nut illustrated in F (see above) goes in such a tight space behind the Oval Muffler weld bracket, that it's near impossible to hold it to torque to 16 lb/ft when the muffler is on the bike. There's near 0 leverage and the way I got to hold it was with a special offset head mini box wrench (12mm). I barely got it in there to hold the nut.
So I hope these notes are helpful. I will post my before & after pics shortly.
This was a great upgrade. The bike sounds amazing, looks amazing, and I can feel the extra torque & power!!!
