The Kawasaki KX 450F is a proven winner! With it's fierce 449cc 4 stroke DOHC engine, superb power delivery, and excellent handling, the KX 450F is certainly a mean cycle! Boasting state-of-the-art power for it's class, it's not hard to see why this bike has so many wins on it's resume. The Kawasaki KX 450F plays to win straight from the factory, however when one needs that competitive edge to take down the competition, this bike accepts modifications extremely well. 


One up the competition on your KX 450F with a Barkers Full Single Exhaust System! A Barkers Full Single Exhaust System will increase performance over the entire power-curve and eliminate that sudden fall-off that your stock system experiences near redline. Not only will your KX 450F rock the track with even more horsepower, it will sound like the mean bike it truly is as it will blast a deep, throaty sound of pure power! When you need to one up the competition, install a Barkers Full Single Exhaust System and hit the track like never before!


Each exhaust system that Barkers Performance manufactures is made of premium materials that are hand-welded right here in the USA. Barkers exhaust systems are hand-welded one at a time by skilled craftsmen, while most other after market exhaust systems are mass produced on large automated assembly lines. This is one of the many reasons that makes Barker's exhaust systems different. The head pipe portion is made from 304 stainless steel that is Tig-welded with seam-reduced interior surfaces for smooth flow. The can is comprised of 6061 grade aircraft aluminum and comes standard in a brushed aluminum finish. You may choose to have your can powder-coated in a black finish for a more customized look. Further enhance your new system by selecting which color Barkers tag you would like. Tag color options are black, bus, red and yellow. To harness your new system to your machine, a strap kit is provided with your purchase.


Additional features for this system include the Barkers Quiet Core Insert and Spark Arrestor. The Barkers Spark Arrestor will help to keep our trails safe by eliminating any flammable debris from exiting the exhaust. The Quiet Core Inserts will reduce sound by up to 5 dB and is ideal for riding in those sound sensitive areas. Besides, with only a loss of .5 to 1.5 horsepower, you might just decide to ride with them in all of the time! 


For serious riding, we highly recommend purchasing a fuel controller for your new system. A fuel controller will drastically improve the way your new exhaust system and Kawasaki KX 450F performs. As your new system will require the added fuel flow, a fuel controller is essential for your KX 450F to perform at it’s best. For optimal results, your dealer or a skilled technician should program the fuel controller prior to installation. If you are interested in learning more about why you should purchase a fuel controller, please feel free to call us! We promise you will talk to a real person who knows all about it!


At Barkers, we have an extreme amount of dedication and respect for the off-road lifestyle. And we understand that owning and maintaining a performance vehicle is no joke. That is why you can expect only the best in Barkers craftsmanship and design. All Barker’s exhaust systems carry a limited one-year warranty against defects in workmanship and/or materials.
