2-Stroke Silencers and Spark Arrestors
Let's me tell you why FMF is our favorite! FMF has radically improved the Power Core 4 for the DRZ by creating a modular end cap that allows for easy tuning alterations. This enables the rider to tune the bike's performance with different end caps that form the powerband around the needs of the rider.
Quickly changed, the standard hi-flo 2" end cap, the original smaller 1-3/4" for smoother power delivery and the spark arrestor module all give the power Core 4 substantial versatility besides offering tremendous performance gains. Tell me that don’t sound good!
