real simple install, once you get the bulky stock can off (semi-hard to get the back springs), 2005 skidoo RT 1000, sounds better the warmer the sled gets. Maybe more popping than rumble sound. Can definatly tell a difference in sound and flow.
The installation was pretty straight forward and simple. The most difficult part of the process was removing the SDI sensor from the stock muffler. With the significant decrease in weight, improved horsepower and performance, this was a smart purchase and positive modification to my sled. (2006 Skidoo MXZ 600 HO SDI Renegade)
Installing this silencer took 10 minutes from start to finish. It has a nice low pitch at idle and isnt loud to the point were the DNR will bother you. All-in-all it is a decent product and if you want a change in tone but not decibles this will be the one.
