Big Gun Exhaust was established in 1997 by former professional motocross racer, Mike Young, Jr., 3-time winner of the AMA National Four-Stroke Championship. He used his knowledge to start a business of manufacturing high-performance exhaust systems for motocross and ATV machines that will surely work great on the track. Side-by-side and street bike markets are covered as well. All high-quality Big Gun Exhaust products are manufactured in the USA with the use of the latest design and production techniques and cutting-edge equipment.
Even though the company has been growing steadily for a decade under Young’s supervision, he decided to sell it to the new owners who could facilitate further growth. The current owner acquired the company in 2010. What followed is a huge restructuring of the assets called to organize the research, development, manufacturing, testing, and distributing operations under one roof in Corona, California. The new management and seals team elevated the Big Gun Exhaust brand to the new level of success thanks to a more efficient manufacturing process. Today, four-stroke Big Gun Exhaust systems can be seen on motocross and street bikes, scooters, sport and utility ATVs and UTVs.
The company’s specialists continue working closely with racing teams, sponsoring different motorsports events, and gathering valuable data for further improvement of Big Gun Exhaust system products. All these facts and an exponential growth over the last few years have solidified Big Gun’s reputation as a reliable and reputable supplier of ECO, EVO, and EXO lines of four-stroke exhaust systems with thick aluminum mufflers and stainless steel head pipes, TFI Power and Rev boxes for ignition and fuel injection timing remapping, as well as a wide range of replacement parts and related accessories, including end tips, spark arrestors, muffler packing kits, muffler cores, heat shields, power box extension harnesses, and more.
