We designed this system stepping up to 1-5/8" pipes for even greater flow and capacity for the Bored and Stroked Raptors out there. If you are planning on many more engine modifications to your motor other than just an exhaust, we would recommend stepping up to the Big Bore system. The good news is that if you've purchased your Raptor 700 system after 2011, if you can easily upgrade to our Big Bore Head Pipe without having to purchase an entirely new system, thus saving a significant amount of money."

The exhaust pipes are made of 304 stainless steel that are Tig-welded with seam-reduced interior surfaces. The cans are comprised of 6061 grade aircraft aluminum and come stock in a brushed aluminum finish. You also have the option to have the cans powder coated in a black finish. For added character you can also chose which color Barker's tag you would like. You can select either black, blue, red or yellow tags. Complete your new Barker's Big Bore Inframe Dual Exhaust by selecting either black, blue or red billet clamps to harness the system to your machine. Other features one should consider are the Barker's Quiet Core Insert and the Barkers Spark Arrestor. The Barker's Quiet Core Insert is ideal for riding in those sound sensitive areas and will decrease sound by up to 5 dB. With only a loss of .5 to 1.5 horsepower, you may consider riding with them in all of the time. For trail safety, install the Barker's Spark Arrestors. Barker's Spark Arrestors will eliminate any flammable emissions from exiting the exhaust. For serious riding, we recommend purchasing a fuel controller for your new system. A fuel controller, like the EHS Fuel Controller, will drastically improve the way your new exhaust system and Raptor 700 performs. When you purchase the EHS Fuel Controller from Barkers, it will have already been pre-programmed to provide your new system with the proper amount of added fuel flow that it requires to perform at its best. 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!
