FMF PowerCore Exhaust System for Honda

The FMF PowerCore exhaust system (also called a PowerCore 4 full exhaust or performance muffler and header system) is a bolt-on upgrade for Honda mini and small-displacement four-stroke powersports machines. It replaces the stock exhaust with a lighter, freer-flowing system built for sharper throttle response and more usable power.

Key Features:

• Full system design with a stainless steel Hi-Flo header and mid-pipe
• Aircraft-grade aluminum canister keeps weight down and adds durability
• Perforated stainless steel Hi-Flo core and formed end cap move exhaust gases efficiently and absorb sound
• Internal packing is designed to last and to spread sound evenly
• Weighs pounds less than the stock exhaust
• Improved throttle response over the stock exhaust
• Made in the USA

FMF designs its four-stroke systems to be dyno-tested and to bolt on with stock hardware locations. Some versions of the PowerCore line are offered with a spark arrestor. The re-packable muffler design lets you refresh the packing as it wears.

Each variant in this line is engineered for a specific Honda model, so choose the part number that matches your machine. Check the manufacturer's notes for each part number about closed-course or off-road use.
