FMF P-CORE 4 YFZ450R ’09-22

U.S. Forestry approved spark arrestor. Megamax II is a reverse cone megaphone design and can be run open for closed course or with discs for off-road riding. FMF has radically improved the PC IV by creating a modular end cap that allows for easy tuning with various end caps that alter the power band around the needs of the rider. Quickly changed, the standard Hi-Flo 2 end cap, the optional 1-3/4 end cap for a smoother power delivery and the spark arrestor module all give the PC IV substantial versatility and tremendous performance gains Includes header*Complete System
