Factory 4.1C Installation
Thank you for purchasing the FMF Factory4.1C as your aftermarket performance exhaust. We have spent
countless hours of R & D and testing to insure you receive the highest quality product on the market today.
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 FEEL THE
POWER!
Please read all instructions thoroughly before installation. Failure to follow all installation instructions completely will void any
FMF warranty implied or otherwise. FMF Racing will not be held responsible for problems derived from improper installation and/or improper
usage.
Before you begin installing this product, be sure you are wearing eye protection and gloves. You should have a complete
understanding of how to remove and replace your stock exhaust. Otherwise you should have it installed by a professional mechanic. Keep all
stock parts when removing stock exhaust as some parts may be necessary to install the FMF exhaust depending on your application.
