If you're looking to give your ride a serious boost, the EVO R series is where it's at. This isn't just another exhaust system; it’s a solid upgrade for your Honda TRX300EX Sportrax or TRX 300X from 2009. Trust me, once you swap out your stock exhaust for this bad boy, you'll feel the difference right away.
Let’s talk about what makes the EVO R stand out. First off, it’s got a hard anodized oval-shaped aluminum muffler that not only looks sleek but also helps save weight. And when you’re out there on the trails, every ounce counts. The TIG welded reinforced muffler brackets mean this thing is built to last, so you won't have to worry about it falling apart on you.
The mid pipe and head pipe are made from 304 stainless steel, which is not just durable but also helps with the overall performance. You’ll notice some serious horsepower and torque gains too—this exhaust really opens up your engine. Plus, the red powder-coated stainless steel end tip adds a nice touch of flair that’s bound to turn heads.
One of the coolest features? The design allows for maximum clearance, so you won’t be scraping on rocks or obstacles while you’re out riding. And if you're in a place where spark arrestors are a must, no worries. This system comes with a removable screen-type spark arrestor, keeping you compliant without sacrificing performance.
All of this is handmade right here in the USA, and you get a 1 Year Limited Manufacturer's Warranty to boot. So, if you’re ready to ditch that stock exhaust and really let your ATV roar, the EVO R is a no-brainer. Just a heads up, it fits perfectly on the specified models, so make sure you’re in the right crowd before you buy!

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.
