SANTA ANA, Calif. - Polaris has unleashed a beast in the form of its new RZR900XP. And Two Brothers Racing has created a new Dual M-7 V.A.L.E. slip-on exhaust system ($699.95) in stainless steel and aluminum.

The M-7 exhaust canister features all of the features found on Two Brothers’ standard street exhaust mufflers along with a removable U.S. Forestry Service-approved spark arrestor.

According to Two Brothers, extensive testing and racing feedback brought horsepower gains across the board to the new system and the RZR900XP.
