- 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
- Not legal for use in California on pollution controlled vehicles, race use only in California - waiver available
