Big Gun 09-13 KTM 450 SX EVO R Series Full System Exhaust

Big Gun is known for building performance exhaust systems that help off-road riders get more out of their machines. This EVO R Series full system is a prime example, designed to give your 2009-2013 KTM 450 SX a serious boost in performance. It’s a tried-and-true setup that not only adds noticeable horsepower and torque but also sounds a whole lot better than the stock exhaust.

This system is constructed with a 304 stainless steel mid-pipe for durability and corrosion resistance, leading to a sleek, hard-anodized oval-shaped aluminum muffler. The muffler design is carefully shaped to provide maximum clearance, so you don't have to worry about it getting in the way during aggressive riding. It also features a TIG welded reinforced muffler bracket for a solid connection. For safety and compliance, a removable screen-type spark arrestor is included, which is crucial for trail riding in many areas. The red powder-coated stainless steel end tip adds a nice visual touch.

Beyond the performance gains, this full system is significantly lighter than your stock exhaust, which can make a difference in how the bike handles. Installation is straightforward, and the handmade quality you expect from Big Gun is evident throughout. This exhaust is built to perform and sound great, giving your KTM 450 SX the power and tone it deserves. Please note that this exhaust is not CARB approved and cannot be shipped to California.
