If you’re serious about your ride, the EXO Stainless Muffler is a game changer. Built from tough-as-nails 304 stainless steel from front to back, this exhaust system is designed to take a beating. I’ve put it through its paces on some pretty rough trails, and let me tell you, it holds up like a champ. We took the original EXO Series and made some solid upgrades: that aluminum muffler has been swapped for a stainless one, and the base plate? It’s now a TIG-welded stainless steel piece that screams durability. Plus, that stamped stainless badge adds a nice touch of flair.
Now, let’s talk features. The muffler itself is made from rugged high-strength 304 stainless steel, so you know it’s built to last. It sports a hexagon-shaped, large diameter housing which not only looks cool but also increases volume. Inside, there's some clever sound wave altering tech that gives you a deeper exhaust tone without being obnoxious. Trust me, you’ll appreciate that on long rides.
The coned inlet is also stamped from 304 stainless steel, allowing for even more volume. And those TIG-welded reinforced brackets? They’re not just for show. They keep everything secure, even when you’re hitting those rough patches. Speaking of hitting the road, the mid-pipe is also made from 304 stainless steel, and the end tip is black powder coated for that sleek look.
Performance-wise, you’re looking at some serious gains in horsepower and torque, which is always a win. Plus, it comes with a removable screen-type spark arrestor, so you can customize your setup a bit. And let’s not forget, this beauty is handmade right here in the USA, which is a nice touch.
Just a heads-up, though: this system isn’t ARB/CARB compliant, so if you’re in California, you’ll have to look elsewhere. But if you’re ready to elevate your Honda Rincon 680 (models 2015-2018), this Big Gun EXO Stainless Slip-On Muffler is definitely worth considering. And it comes with a 1 Year Limited Manufacturer's Warranty, so you can ride with confidence.

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.
