Yamaha® Kodiak 450

The Yamaha® Kodiak 450 is available in the HMF™ Performance and Titan Series as a Slip-On System.  The Performance Series and Titan Series both picked up 2-3 horsepower and 2-3lb of torque.  The Performance and Titan-XL (extra loud) were 4-6dB louder than the stock muffler, while the Titan-QS (quiet) was roughly 1-2dB louder, all of which added a deep and aggressive sound to the Kodiak.
