Built with an aluminum canister and a stainless mid-pipe and end cap, the 2.1 delivers a smooth power curve throughout the rpms while still coming in at a lighter weight than your stock setup. That’s even considering the larger diameter canister that allows for more packing material and longer service intervals.
But, the 2.1’s main claim to fame is its integrated USFS approved "Turbine Dampening System" spark arrestor. This system prevents all sparks from exiting the exhaust, but it doesn’t choke the flow of exhaust gases like a screen-type arrestor can. It’s also essentially impossible for the Turbine Core to become clogged by residual oil or "spooge" as is common with screen arrestors.
