FMF Turbinecore 2 Silencer Exhaust. FMF starts the Turbine Core II with an aluminum alloy canister, stainless end cap, and stainless midpipe that give the silencer an excellent amount of durability and quality.
I bought a bike with the FMF fatty and power core silencer already on it. I needed a silencer that had a spark arrestor for trail riding so this was a perfect fit.
