We are proud to sponsor Juan Pirrunas Dominguez, who races competitively in the SCORE International desert racing series. The SCORE International races are some of the toughest, most brutal races held in southern California and Mexico. Desert racing makes for intense heat and terrain, and we could not be more proud at how our sponsored rider, Juan, and our exhaust system hold up against these extreme elements. You can learn more about Juan and our exhaust by reading our blog articles: Barker's Sponsored Rider, Juan Pirrunas Dominguez Wins 2017 San Felipe 250, and Barker's Sponsored Rider, Juan Pirrunas Dominguez Ready To Win SCORE International San Felipe 250.

Each and every system that Barkers Performance produces is made of premium materials that are hand welded right here in the USA! While other after-market exhaust systems can be mass produced from automated assembly lines, Barkers exhausts systems are hand-welded one-by-one by skilled craftsmen. The head pipe portion of your new system 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. For a more customized look, you may choose to have your can powder-coated in a black or red finish. You may also select which color Barkers tag you would like. Tag color options are black, blue, red or yellow. To harness your new system to your machine you may choose black, blue or red billet clamps. 


Other features are available for your new Full Single Exhaust System as well, and include the Barkers Quiet Core Insert and Barkers Spark Arrestor. The Barkers Spark Arrestor will eliminate any flammable debris from exiting the exhaust and will help to keep our trails safe! When riding in those sound sensitive areas, the Barkers Quiet Core Insert will help to reduce sound by up to 9 dB. Heck, with a loss of only .5 to 1.5 horsepower you might want to ride with them in all of the time! 


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.
