The Yamaha Kodiak 400 has a liquid-cooled, 401cc, SOHC, 4-stroke engine that is the best-performing engine in its class. When we started developing the Slip-On exhaust system, we realized the potential power that was at our fingertips. We were able to increase the horse power 7% with the HMF Performance Series installed on the bike. We also were able to decrease the sound 2-4 dB with the optional HMF Quiet Core installed.

Exhaust Series We Recommend:
Penland Pro Series
The Penland has the same core as the Performance Series, but features the removable TRM that allows quads to hook-up better in rough conditions.
Other Exhaust Series Available:
Quiet Race Series
|The HMF Performance Series has a specially designed, unrestricted core that allows the exhaust to increase power evenly throughout the entire power curve. It also features the signature HMF sound with industry-leading end cap and color options, giving you a completely custom look.
|The Quiet Race Series is designed for race vehicles and meets most sound regulations on the track while still delivering horse power gains throughout the power curve. When compared to the Performance Series exhaust with an HMF Quiet Core installed, the QRS delivers less dB.
Each HMF Exhaust:
Whenever you add an after-market exhaust system to your machine, tuning your carburetor is, in most cases, an absolute necessity. The proper jets and EFI settings are extremely important for the performance and lifespan of your machine. Tuning Kits
are available to ensure your machine runs at it's top performance and your HMF Warranty remains valid.
