I installed my own, took less than an hour. It's a pretty simple install.
Remove the fairings (both sides). Loosen the three bolts holding the stock muffler (2 left side, 1 right side), Loosen the clamp on the header. Remove remaining bolts and remove the muffler.
Apply Akrapovic copper anti-seize to new clamp and clamp bolt. Install link pipe onto header with clamp, install retention spring (at this pooint it's easier NOT to tighten the clamp, so you can make sure the pipe is rotated in the right position when installing muffler).
Install hanger bracket. Slide muffler clamp over muffler and install muffler onto the link pipe using two rentention springs. After lining everything up, tighten it all down and reinstall your fairings.
It's really easy.
