This muffler uses all of the stock mounting points and hardware. It comes with the new Speedwerx performance guarantee to assure you it will not hurt the performance of your machine. Our extensive testing process and years of experience allow us to offer this performance guarantee. We have tried over 10 different versions and variations in our testing on the new platform and it has been challenging to say the least, this new platform is very sensitive to the muffler design. Muffler is made out of mild steel and ceramic coated for heat retention and appearance reasons. Offers a stock like sound with a deeper tone. This is our quiet trail can.
