How is a Barker's Grizzly 550 Slip On different from other slip on exhaust brands?
Barker's Slip On exhausts are not your typical “Straight Pipe into a Can” that solely makes your machine louder. Others produce slip on exhausts that don't actually increase horsepower or improve the machine's functionality, they only increase the sound thus providing a false sense of increased speed. Our Slip On exhausts fully utilize our Reverse Megaphone design with our pulse wave technology, which are meticulously tested and tuned to achieve the most performance. We refuse to sacrifice and offer something that doesn’t make power, and you can expect our slip on to deliver more than our signature Barker's sound!
THE FULL STORY:
When you need an ATV to take on the challenge of heavy duty work while powering over rough terrain, the Yamaha Grizzly 550 is the sport utility ATV to make it happen.

Taking on the dirty jobs never felt so good, when you ride a Yamaha Grizzly 550!
If you are looking for a cost-effective solution to take your Yamaha Grizzly 550 to the next level, install a Barker's Slip On Exhaust System! The Barker's Slip On Exhaust is simple to install and will deliver that deep, throaty Barker's sound that will bring your Grizzly 550 to life.

All of Barker's Exhaust Systems are made from premium materials that are hand welded in the USA. The exhaust pipe is comprised of 304 stainless steel that is Tig-welded with seam-reduced interior surfaces. The can is made from 6061 aircraft grade aluminum and comes standard in a brushed aluminum finish. You can also choose to have your cans powder coated in a black finish for a more personalized look. Finalize your new Slip On Exhaust by selecting which color Barker's Tag you would like. The color options are black, blue, red and yellow. A Strap Kit is included with your purchase to harness your new system to your machine.
One might also consider also purchasing our Barker's Quiet Core Insert and Spark Arrestor. The Spark Arrestor will assist in keeping our trails safe by eliminating any flammable emissions from exiting the exhaust. The Quiet Core Inserts are ideal when riding in those sound sensitive areas. The Barker's Quiet Core Inserts can reduce sound by up to 5 dB and with a loss of only .5 to 1.5 horsepower you just might want to ride with them in all of the time!
At Barker's, we have an extreme amount of dedication and respect for the off-road lifestyle. And we understand that owning and maintaining a performance vehicle is no joke. That is why you can expect only the best in Barker's craftsmanship and design. All Barker’s exhaust systems carry a limited one-year warranty against defects in workmanship and/or materials. See Barker's Terms & Conditions.
We recommend that you monitor and check the packing in your muffler after every ride. The length and time your packing will last will vary depending on how and where you ride. When you first notice any sign of the packing depleting within the can, it's time for a repack. Packing will wear out slowly over time, starting at 100% packed. It is normal for an absorption style high-performance muffler to lose packing but once you lose more than about 10-15% of your packing it will deplete faster and faster since it can now move around in the can. It is imperative you do not allow the packing to deplete too far. If your muffler becomes very loud or you hear rattling around inside the can you have completely depleted the internal packing and should not ride the machine until the muffler is repacked with a fresh pillow. Order new packing before you need it!
The Barker's Exhaust Complete Repack Kit is designed to make repacking your Barker's Exhaust Can simple.
