BARKER'S ENGINEER COMMENTS:  

"Being that we were so successful in creating horsepower on the Raptors, we were excited to see that Yamaha used the same motor in their Grizzly. The motor is set up slightly different for this sport/utility machine but it still loved the Barker's system on there. As you can see from the Dyno Charts, once you add the proper fuel required after installing the Barker's exhaust system, we achieved some pretty respectable numbers. As is the case with most of our exhaust systems, the fuel/air ratio will drop or lean out a bit due to the added flow delivered by our exhaust. A solid 4 additional horsepower with 3 ft-lbs. of torque gain was achieved once the system was properly tuned. This is why we always recommend professional tuning or adding a pre-loaded rule controller that have been specifically Dyno tuned for the machines. Thanks to EHS for the superb tuning they did on this machine for us; we highly recommend including their fuel controller for this system when placing your order." 

THE FULL STORY:

When you need to get the job done right the first time, the Yamaha Grizzly 550 is the utility ATV to make it happen. Over the most intense terrain and gnarly conditions, the Grizzly 550 is real-world tough. With the non-compromising performance, agile and precise handling, and a powerful 558cc engine, Yamaha’s Grizzly 550 is ready to take on any job, anywhere. 

If you want to take your Grizzly 550 to the next level, install a Barker's Full Dual Inframe Exhaust System. With a Barker's Full Dual Inframe Exhaust and a properly mapped fuel controller, your Grizzly 550 will gain up to 4 more horsepower and up to 3 more ft-lbs of torque! Installing a Barker's Full Dual Inframe Exhaust System will also give your Grizzly that deep, throaty sound you’ve been searching for! For optimal results, we highly recommend purchasing the EHS Racing EFI Fuel Controller. When you purchase the EHS Fuel Controller from Barker's, we have already pre-mapped the controller with the specific dyno data for your individual system. Having the EHS Fuel Controller installed alongside your new Barker's system will provide the much-needed additional fuel flow to make your Yamaha Grizzly 550 roar!
