Can-Am® DS90

The Can DS90 is available as a Slip On System in the Performance Series exhaust. The shell is a miniature version of the standard Performance, and features an internal core that is sure to make the most of these smaller engines. There is typically a 10-15% horse power and torque increase on the Can Am DS90, and the sound level should be roughly 2-3dB louder than the stock muffler.

Note: The Can Am DS90 exhaust system does not come with a Spark Arrester. Call 866.HMF.PIPE to have one installed.

Fits: (13-14) Can Am DS90, X
