If you’re looking to amp up the performance of your mini MX or ATV, the EVO M series is where it’s at. This isn’t just another exhaust—it's been a go-to for over a decade, and for good reason. Sure, it’s evolved over the years, but the core objective has always been the same: to give you that noticeable performance boost that makes a real difference. The deep, throaty growl it produces? It’ll take you back to when you were a kid, feeling that thrill all over again.
This exhaust system is designed for a range of 50cc-110cc models, so whether you’ve got a Honda CRF50F or an XR50R, you’re covered. The black powder-coated aluminum muffler not only looks sleek but is built to last. And the mid pipe and head pipe? They’re made from TIG-welded 304 stainless steel, which means you’re getting durability without the extra weight. In fact, this setup is lighter than the stock exhaust, making it a no-brainer for anyone wanting to shed some pounds off their ride.
But let’s talk about the real perks: you’ll notice significant gains in horsepower and torque. That’s what it’s all about, right? Plus, the design of the muffler ensures you won’t have to worry about clearance issues, giving you that extra edge on the track or trail. The removable screen-type spark arrestor is a nice touch too—safety first, after all.
And just to keep things straightforward, this beauty is handmade right here in the USA, which speaks volumes about the quality you’re getting. Plus, it comes with a 1-year limited manufacturer’s warranty, so you can ride with peace of mind.

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.
