If you're looking to amp up the performance of your mini MX or ATV, the EVO M series exhaust is where it's at. This isn't just another exhaust system; it's been a staple in the Big Gun lineup for over a decade, and for good reason. I’ve had the chance to put this system through its paces, and I can tell you, the changes and improvements they’ve made over the years really shine through. The deep, throaty sound it produces? It’s enough to make you feel like a kid again, no matter how old you are.
Now, let's talk specifics. This exhaust is designed for a range of 50cc to 110cc models, so whether you’re cruising around on a Honda TRX 90 or another mini beast, you’re covered. The black powder-coated aluminum muffler not only looks sleek but is also durable. Plus, the TIG welded 304 stainless steel mid pipe and head pipe ensure that you’re getting a solid build that can handle some serious rides.
One of the best parts? It’s lighter than the stock exhaust system, which means you’ll feel that boost in performance right away. We’re talking about significant horsepower and torque gains here—enough to make a noticeable difference on the track or the trails. And the design? It’s sleek and allows for maximum clearance, so you won’t have to worry about snagging on obstacles.
Oh, and if you’re concerned about safety, it comes with a removable screen-type spark arrestor, which is a nice touch for those of us who like to ride responsibly. Everything is handmade in the USA, and you even get a 1-year limited manufacturer’s warranty to back it up.
For fitment, this bad boy is perfect for the Honda TRX 90 from 1993 to 2005. If you’re rolling with a Honda Moto TRX90 Sportrax during those years, the 10-1903-BK Big Gun Evo M Full System Black Out Edition is a match made in heaven.
So, if you’re ready to unleash some serious power and sound from your ride, the EVO M series is definitely worth considering. Trust me, you won’t regret it.

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.
