Big Gun has a long history of building power for off-road machines, and the EVO R series is a testament to that experience. You'll notice a substantial weight savings compared to the stock setup, which can make a big difference when you're out on the track or trail. This system is also engineered to unlock noticeable horsepower and torque gains, giving your KX 450F a stronger pull and better overall response. The muffler itself features a sleek, oval-shaped aluminum body that's hard anodized for durability, and it's designed to provide maximum clearance so it doesn't get in your way. The mid and head pipes are constructed from 304 stainless steel, known for its strength and resistance to corrosion. Everything is TIG welded for solid connections, including the reinforced muffler bracket(s). It even comes with a removable screen-type spark arrestor, which is important for trail riding regulations.

This exhaust system is handmade right here in the USA. It's important to note that this system is not CARB approved and cannot be shipped to California. You'll also get a 1-year limited manufacturer's warranty for peace of mind. If you're aiming for improved performance and a much better sound from your KX 450F, this Big Gun EVO R system is a solid choice.
