Based on the large Monster muffler design, EC Twin Slash Monster slip-ons feature the signature Vance & Hines twin slash end treatment and full coverage heat shields to ensure a blue-proof show quality finish.

EC Twin Slash Monster slip-ons are type-approved for all 2009-2011 Harley-Davidson Touring models equipped with the Twin Cam 96 powertrain, and utilize an innovative four-stage sound insert to meet the strict sound level standards enforced in the European Union.
