RoadsterSport RACE Single Stainless Steel Muffler

The RoadsterSport RACE Single Stainless Steel Muffler is specifically engineered for racing applications, targeting autocross and track drivers of the 2006-2015 Mazda MX-5. It provides a simplified, single-sided exhaust setup, addressing concerns about the weight and performance benefits of dual exhausts on a four-cylinder engine. This muffler is noted for its aggressive tone, with recorded sound levels typically between 85-88 db at 50 feet, which is generally within track and autocross limits. Constructed from polished stainless steel, the muffler weighs just 8 pounds, representing a significant weight reduction of nearly 20 pounds compared to the factory exhaust. This is achieved through a straight-through, high-density core with a high perforation rate, balancing sound suppression with minimal weight. It does not include a baffle insert, but an optional baffle is available separately. The product is proudly made in the USA and comes with a lifetime warranty. It uses stock hangers and connects to either the stock or an aftermarket midpipe, including mounting hardware and gasket. It delivers a classic sports car bark when accelerated, while remaining relatively mild during cruising on an otherwise stock vehicle. However, the "right" sound level is subjective, and the manufacturer notes that customers under 30 generally perceive it as not too loud. Installation notes recommend lubricating hangers with dish soap for proper flange alignment and torquing hardware to no more than 25-30 ft/lbs to ensure a proper seal.
