Thank you for your interest in CHM Performance Exhaust. With over twenty five years experience in high performance 4-stroke design and manufacturing, we strive to produce only the finest exhaust systems for dirt and street.

Whether on the race track or our in-house dynamometer, each system is tested thoroughly to assure peak performance. Our high strength 304 stainless exhaust headers are lightweight yet ultra durable. Why pay more for titanium systems which are only a few ounces lighter, more prone to breaking and cost 30-40 % more. We feature Hi-Tech packing material for longer life with less sound. Our anodized mufflers feature a removable USFS qualified spark arrestor and an optional db cartridge to lower noise levels up to 7 db’s without killing performance. 
 

In our first year on the market CHM Performance Exhaust systems dominated CYCLE WORLD magazine’s Super TT series winning titles in Premier, Open, and Mini Motard classes, all with different riders! Move to the front of the pack with CHM Performance Exhausts.  

       

07 YZ 450F - OVATE SYSTEM - P/N 04-1014

 

New things are coming from CHM. Take our new YZ 450F system. A new design from the ground up. Our close-fitting, stepped header combined with our redesigned OVATE aluminum canister substantially increase performance throughout the entire rpm range. We’ve added an FIM compliant formed, stainless end cap with matching rivet straps for increased strength and a new look. Initial feedback from our Yamaha customers has been amazing.
