Thank you for purchasing the FMF Titanium 4 exhaust for your 

CRF50/XR50

. We have spent 

countless hours of design work and testing to insure you receive the highest quality product on the market
today.

Your Titanium 4 exhaust has been developed using the latest design, testing and manufacturing 

technologies. It is manufactured from military grade titanium with a titanium TIG welded mid pipe and 
header, modular endcap and uses space age sound-absorbing packing material.

The Titanium 4 exhaust is designed to broaden your existing powerband and give you an all around

power increase with substantial weight savings.

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. If you do not, you should have it installed by a professional mechanic. Keep
all OEM parts when removing your stock exhaust, as some parts may be utilized with the FMF exhaust depending on your particular 
application.
