If you're looking to give your ATV or Side x Side a serious upgrade, the EVO U Series Slip-On Muffler is where it's at. This isn't just some generic exhaust; it's crafted for those who crave that deep, throaty growl that makes your ride stand out. Designed specifically for utility and sport utility ATVs, it delivers raw power that’ll get your adrenaline pumping.
Let’s talk about the construction. This bad boy features a high-temp black thermal coated oval-shaped aluminum muffler that not only looks sleek but also holds up against the heat. The TIG welded reinforced muffler brackets ensure it stays put, no matter how rough the terrain gets. Plus, the 304 stainless steel mid-pipe means you're not just getting a pretty face; it’s built to last.
One of the best parts? It’s way lighter than your stock muffler, which translates to massive horsepower and torque gains. So, if you've been stuck with that restrictive, tinny stock exhaust, swapping it out for the EVO U will feel like night and day. You’ll notice the difference right away, whether you're climbing hills or cruising the trails.
And it doesn't stop there. The sleek design allows for maximum clearance, so you won’t have to worry about snagging on rocks or roots. Plus, it comes with a removable screen-type spark arrestor, just in case you need to keep things safe while still enjoying that killer sound. Oh, and if you want to tone it down a bit, the Vortex Quiet Insert is included, giving you options depending on your mood.
Handmade in the USA, this muffler also comes with a 1-Year Limited Manufacturer's Warranty, so you can ride with confidence. If you're ready to unleash the true potential of your Polaris ACE 570 (2015-2018), the 12-7322 Big Gun EVO U Slip-On Muffler is a no-brainer.

Big Gun Exhaust was founded in 1997 by former professional motocross racer, Mike Young, Jr., a three-time winner of the AMA National Four-Stroke Championship. He knew what it took to win the races and used that knowledge to start a business of manufacturing high-performance, quality exhausts for the motocross and sport ATV market, and eventually the side-by-side and street markets as well.
New Ownership, New SuccessAfter more than a decade of success under Young, Big Gun Exhaust was sold to a new owner in the hopes of facilitating further growth. In 2010, the company changed ownership once more, which called for tremendous restructuring in an effort to improve the brand. The new management and sales team helped rebuild the Big Gun Exhaust brand and streamline production and manufacturing processes under one roof in Corona, California. The more efficient manufacturing process resulted in a new level of success never before seen with Big Gun. Today, Big Gun Exhaust boasts one of the largest four-stroke exhaust product lines available and caters to the MX, Sport ATV, Utility ATV, Side-by-Side, Street, and Scooter markets.
