FMF 042388 Q4 HEX S/A Slip-On Muffler Aluminum Spark Arrestor

The FMF 042388 Q4 HEX S/A is a single slip-on muffler (silencer) for off-road exhaust systems. It is built to cut noise while keeping power gains across the rev range, so you don't have to settle for a restrictive, power-robbing quiet muffler.

Key Features:

• Slip-on design in a single configuration
• Aluminum construction with a natural finish
• Stainless steel midpipe and stainless steel endcap
• Internal chambers, baffles and multistage packing material for quiet operation
• Spark arrestor screen insert included
• 94dB quiet insert included
• Meets USFS and FIM World Enduro sound regulations
• Weighs 6.6 lbs.

Please note: FMF lists this item for closed course use only and gives it a CARB warning.

With the Q4 HEX you can feel the power without hearing it. It is lighter than a stock muffler and has a rugged design for off-road use.
