Big Gun 11-12 KTM 450 SX-F EVO R Series Full System Exhaust

This is the Big Gun EVO R Series full system exhaust, designed specifically for the 2011 and 2012 KTM 450 SX-F. If you're looking to get more out of your bike, this exhaust is a solid choice. It's built to replace your stock system, offering a significant improvement in both performance and sound.

The EVO R series is known for its ability to make power, and this system is no exception. It's constructed with a 304 stainless steel mid and head pipe for durability and corrosion resistance, while the muffler itself is made from hard-anodized oval-shaped aluminum. This construction not only looks sharp with its red powder-coated stainless steel end tip but also helps reduce overall weight compared to the stock exhaust. The TIG welded reinforced muffler bracket ensures it stays securely in place. You'll notice a substantial increase in horsepower and torque, and the sound will be much more aggressive than your stock setup. Plus, it includes a removable screen-type spark arrestor, which is important for off-road riding.

This exhaust system is handmade in the USA and comes with a 1-year limited manufacturer's warranty. Keep in mind that this system is not CARB approved and cannot be shipped to California. For installation, refer to the manufacturer's instructions for proper fitment and mounting.
