If you're looking to give your Polaris Outlaw 525 IRS a serious boost, the EVO R series is where it's at. This isn't just another exhaust; it's a piece of gear that brings some serious performance to the table. I've put this slip-on muffler through its paces, and let me tell you, the difference is night and day compared to the stock setup.
First off, the hard anodized oval-shaped aluminum muffler is not just for show. It’s lightweight, which means you’re shedding some serious pounds off your ride. And the sound? It’s a whole new level of awesome. You’ll turn heads and make your presence known on the trails.
One of the standout features for me has been the TIG welded reinforced brackets. You can tell this thing is built to last, and it feels solid even when you're pushing it hard. Plus, the 304 stainless steel mid pipe ensures that you’re getting both durability and performance. It’s resistant to rust and corrosion, which is a big deal if you’re out riding in less-than-ideal conditions.
The red powder-coated stainless steel end tip adds a nice touch of flair, and it’s not just for looks. It helps with the exhaust flow, which means better performance overall. I’ve noticed some impressive gains in both horsepower and torque, which makes tackling those steep inclines a lot more fun.
Another thing I appreciate is the removable screen-type USFS approved spark arrestor. It gives you the freedom to customize your setup while staying compliant with regulations, which is a must for any serious rider.
And let’s not forget, this beauty is handmade right here in the USA. You’re not just getting a product; you’re supporting local craftsmanship. Plus, it comes with a 1-year limited manufacturer's warranty—just in case you run into any issues.
So, if you own a Polaris Outlaw 525 IRS from 2007 to 2011, this is the exhaust you want to consider. The Big Gun EVO R Slip On Muffler is a game-changer, and I can’t recommend it enough if you’re serious about enhancing your ride.

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.
