If you're looking to kick your ride up a notch, the EVO R series is where it's at. This isn't just another exhaust; it's a piece of engineering that pulls from a long legacy of power and performance. Designed for various off-road MX and sport ATV models, the EVO R has proven itself time and again. You’ll notice the weight savings right away, and trust me, the performance boost is nothing short of impressive. Plus, it sounds way better than your stock setup—think of it as giving your bike a voice that actually matches its spirit.
Let’s talk about what makes this exhaust stand out. The hard anodized oval-shaped aluminum muffler is not just for show; it’s built to last and handle whatever you throw at it. The TIG welded reinforced muffler brackets ensure that everything stays secure, even when you're hitting those rough trails. And the 304 stainless steel mid pipe and head pipe? They’re not just durable; they really enhance the overall performance. You’ll feel the huge horsepower and torque gains when you twist the throttle, making those climbs and sprints feel effortless.
One of my favorite features is the sleek design. It allows for maximum clearance, which is a game-changer when you're navigating tight spots or tackling tough terrain. And if you're worried about sparks flying during your adventures, the removable screen-type spark arrestor has got you covered. It’s handmade in the USA, so you know you’re getting quality craftsmanship, and it comes with a 1-year limited manufacturer’s warranty for peace of mind.
Now, if you ride a Kawasaki KX 450F from 2009 to 2011, this exhaust is specifically designed for you. The fitment is spot-on, and you won’t have to worry about compatibility issues. It’s the perfect upgrade to transform your ride into something that’s not just fast, but also sounds incredible.
So, if you’re ready to ditch that stock exhaust and experience a whole new level of performance and sound, the Big Gun EVO R Full System 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.
