Pro Circuit: Built on Racing, Refined by Champions
Pro Circuit is one of the most decorated names in motocross performance history. Founded in 1978 by desert racing pro and motor tuning specialist Mitch Payton, the brand grew from a single speed shop in Southern California into a globally recognized force in off-road and supercross racing. Payton's reputation for cylinder porting and polishing spread quickly through the southern California racing community, and it wasn't long before custom-tuned exhaust pipes became the first signature Pro Circuit high-performance accessory — a legacy the brand still leads with today.
What separates Pro Circuit from the competition is a racing heritage that goes beyond marketing. The brand fields one of the most successful factory-supported amateur-to-pro pipelines in American motocross history. Early team alumni include future champions Jeremy McGrath and Ricky Carmichael, and the program has gone on to claim over 29 AMA Championships and multiple Motocross of Nations victories. That level of championship experience doesn't just build trophies — it feeds directly into product development, ensuring every component that leaves the facility in Corona, California has been race-tested by riders competing at the highest levels.
Exhaust Systems: The Core of Pro Circuit's DNA
At the heart of Pro Circuit's catalog are their world-class exhaust mufflers and systems, available for two-stroke and four-stroke dirt bike engines across a wide range of popular makes and models. Their flagship Ti-6 and Ti-6 Pro titanium exhaust systems are engineered for riders competing in AMA Supercross and AMA Motocross, featuring full titanium construction throughout the head pipe, mid pipe, and canister, with a carbon fiber end cap for maximum weight savings. The newer Ti-6 BC ("Big Canister") system builds on this platform with an asymmetrical muffler design that increases packing volume to meet the latest AMA and FIM sound regulations — without sacrificing power output.
Pro Circuit's exhaust lineup extends well beyond the professional podium. Their T-6 stainless steel systems and Platinum pipe offerings cater to off-road riders, trail enthusiasts, and even mini bike racers, with fitments for small displacement bikes from 50cc up through 85cc and 100cc classes. ATV riders are also covered, with exhaust options including Platinum pipes and Type 296 spark arrestor silencers suited for recreational and competitive use. Every system is developed in-house and rigorously tested by Pro Circuit's race team and support riders before it ever reaches a customer.
Whether you're chasing a championship gate, shredding trails on the weekend, or simply looking to squeeze more power out of your machine, Pro Circuit's exhaust systems represent decades of refined engineering and race-proven performance. Their commitment to quality materials — titanium, stainless steel, and carbon fiber — combined with precise TIG welding and exact-fit engineering, makes them a trusted choice for serious riders worldwide.
