    Hand Crafted Performance Exhausts

    Stone Racing, LLC is the Registered Trademark owner of ProRacing® Exhaust systems, an award-winning Performance exhaust for Superbikes, Street Bikes and Sportbikes.  ProRacing® Exhaust is a US company and brand located in a suburb of Reno, Nevada.  Our motorcycle range encompasses a wide selection of silencer styles to match your exact requirements --  from our entry level 'Factory' OEM silencer, to the Grade 1 Aerospace Titanium.

    We use only the very best 304 grade stainless steel and 3K weave carbon fiber.  All our systems are made from 304 grade polished stainless steel, 3K carbon Fiber, or Grade 1 Aerospace Titanium, (or a combination, depending on the style) and come with a two-year unlimited mileage warranty.  All our systems are handmade, and hand welded for beauty and performance.

    You only have to hold a ProRacing® exhaust to appreciate the premium design and construction qualities, which translate into tangible gains in both performance and reliability. Hand crafted and widely regarded as the best bike exhaust on the market today, ProRacing® has become one of the most popular upgrades a rider can make.

    The real difference is the way a ProRacing® feels. No other exhaust is created with our passion, expertise and experiences. Everything that we have put into developing the world’s best exhausts over the years is designed to be shared, felt, and experienced by you, the rider.

    It was our engineering, workmanship and testing that built the full titanium system (Grade 1 Aerospace Titanium) that won the world championship at the World SBK in Portugal this past September. Our system gave 2 more horsepower than any of its performance competitors. This bike with our exhaust, achieved the Highest Top Speed and won the World Championship.

    In Germany this past year, our Yamaha R1 Link Decat Pipe added an additional 3 horsepower over a well-known performance exhaust made in Slovenia.

    For many years our exhaust systems have sold under other popular names around the world.  As of this year ProRacing® is now available in the U. S.  We are currently in the process of selecting dealers across the United States and Canada.
