Big Gun 03-06 Yamaha GRIZZLY 660 EVO U Series Slip On Exhaust

The 304 stainless steel mid-pipe on this Big Gun EVO U Series slip-on exhaust is a solid choice for your 2003-2006 Yamaha Grizzly 660. This exhaust is built to give your utility ATV a serious sound upgrade, moving away from the restrictive stock tone to something much deeper and more powerful. It’s designed to handle the demands of utility ATVs and side-by-sides, so you know it’s well-built for the job.

You'll notice the sleek, oval-shaped aluminum muffler, which is coated with a high-temperature black thermal coating to handle the heat. This design also helps keep the muffler tucked up nicely, allowing for maximum clearance when you're out on the trail. It comes with a removable screen-type spark arrestor, which is important for safety and trail regulations, and a black powder-coated stainless steel end tip for a clean look. The TIG welded reinforced muffler bracket means it’s attached securely.

This system is handmade in the USA and is significantly lighter than your stock exhaust, which can make a difference in how your ATV handles. It also includes a Vortex Quiet Insert if you need to tone down the sound a bit, though this series is known for its aggressive tone. Keep in mind this exhaust is not CARB approved and cannot be shipped to California.
