EXO Stainless is the most durable exhaust in our lineup. Constructed of high-strength 304 stainless steel from front to back, EXO Stainless is sure to withstand even the most brutal of riding conditions and use. We took the original EXO Series and swapped out the aluminum muffler for a stainless muffler, replaced the aluminum base plate with a TIG-welded stainless steel plate and added a trick looking stamped stainless badge to top it off.

About Big Gun Exhaust

About Big Gun Exhaust

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 Success

After 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.
