Big Gun 03-06 Kawasaki KFX 400 EVO R Series Full System Exhaust

When you open the box for this Big Gun EVO R Series Full System Exhaust, you'll find the complete package ready for installation on your 2003-2006 Kawasaki KFX 400. This system includes a sleek, hard-anodized oval-shaped aluminum muffler with a red powder-coated stainless steel end tip, a 304 stainless steel mid-pipe, and a removable screen-type spark arrestor. The muffler bracket is TIG welded for reinforcement, ensuring it holds up to the rigors of off-road riding.

This exhaust system is designed to make a real difference in how your KFX 400 performs. It's significantly lighter than the stock exhaust, which helps with overall handling and agility. You can expect substantial gains in horsepower and torque, giving your ATV a much more responsive feel. The construction is well-built, with the mid-pipe made from durable 304 stainless steel and the muffler bracket TIG welded for added strength. The muffler itself is hard-anodized aluminum, offering a good balance of durability and weight savings, and the red end tip adds a custom look.

Installation is straightforward, and the muffler design allows for maximum clearance, so it shouldn't interfere with your riding. Remember that this exhaust is handmade in the USA and comes with a 1-year limited manufacturer's warranty. Please note that this system is not CARB approved and cannot be shipped to California.
