The Arctic Cat Wildcat Trail is available as a Slip-On system in the Performance and Titan. Depending on the exhaust series, the slip-on system picks up 10-15% more horse power and torque throughout the power curve, and remains substantially less that the stock exhaust. The Performance and Titan-XL exhausts are typically 4-6 decibels above the stock muffler, while the Titan-QS is 1-2dB. Each exhaust can use the HMF Quiet Core insert for a 1-2B drop in sound.
