Factory 4.1C Installation
Thank you for purchasing the FMF Factory4.1C as your aftermarket performance exhaust. We have spent

All FMF's products are developed using the most current technology available for design and manufacturing.
We use only the highest quality materials for function and durability. The Factory 4.1C muffler is constructed of
a carbon fiber canister with a titanium mandrel bent midpipe. Tru-Flo modular titanium endcaps are fitted to both
ends and we utilize advanced multistage sound absorption packing material.
The Factory4.1C muffler is the lightest slip on muffler available and specifically engineered to broaden
your existing powerband to give you an all-around power increase. Bolt on FMF performance and

REMOVAL
Carbon mufflers are less durable than titanium or aluminum and are more easily damaged from a crash
as well as normal riding. Damage to the muffler will result from improper maintenance. Replace
packing if there is indication of packing blow out as evidenced by discoloration of muffler canister (gray
carbon weave turning brown), increased exhaust sound level or change in performance. Always
replace packing material if water gets into the muffler. Warranty is limited on this product.
