If you're looking to upgrade your ride, the EXO Series exhaust is where it’s at. Born from a need for something that could keep up with the beefier sport ATV engines, this exhaust system is all about performance and sound. The hexagon-shaped aluminum design isn’t just for show; it’s engineered to handle more volume, which means you’re getting a deeper, more aggressive tone without being over the top. It’s the kind of sound that makes you feel like you’re truly in control of your machine.
One of the standout features is the lightweight brushed aluminum construction. This stuff isn’t just light; it’s tough, too. The large diameter housing allows for more airflow, which is crucial when you’re pushing your ATV to its limits. Plus, the internal sound wave technology helps fine-tune that deep growl you want while keeping it tolerable, so you can enjoy the ride without annoying the neighbors.
Then there’s the stamped 304 stainless steel coned inlet. This isn’t just a fancy term; it actually helps to increase volume even further. And let’s not forget about the TIG welded reinforced brackets—these are built to last and keep everything secure, even when you’re tearing through rough terrain. The mid pipes and head pipes are also precision TIG welded and CNC bent from 304 stainless steel, ensuring a perfect fit and durability.
When it comes to performance, you can expect some serious gains in horsepower and torque. This isn’t just about making noise; it’s about making your UTV perform better. And for those who are a little more safety-conscious, it comes with removable screen-type spark arrestors, which is a nice touch if you’re hitting the trails.
Handmade right here in the USA, the EXO Series is designed for the Yamaha YXF850 Wolverine X4 from 2018 to 2020, and it comes with a 1-year limited manufacturer’s warranty for peace of mind. If you’re ready to take your ATV to the next level, this slip-on exhaust is definitely worth considering.

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.
