In 1978, desert racing pro and tuning specialist Mitch Payton opened a shop called Pro Circuit. Rumors of Payton’s motor building skills quickly spread and like all small companies, a cult following ensued. Once he mastered cylinder porting and polishing, Payton looked at other bike parts and soon after custom-tuned exhaust pipes represented the first Pro Circuit high-performance accessory.
Once again, the word got out and requests for modifications to other parts of a dirt bike followed. A suspension shop opened and Pro Circuit expanded their line of exhaust systems. In 1991, Payton took a four-man team which included an unknown Jeremy McGrath and competed in the AMA Supercross series sweeping the 125cc East and West championships. In 1997, another unknown rookie named Ricky Carmichael took the 125cc National Motocross championship. The rest as they say, is history.
Pro Circuit manufactures exhaust systems for 2-stroke and 4-stroke engines which includes exhaust inserts, slip-ons, spark arrestors, end caps, head pipes, mid pipes and replacement silencer canisters. Pro Circuit exhaust systems range in price and some are best suited for certain bikes over others.
