Description
Performance Race Muffler. The Flowmaster Outlaw Series Center/Center Shorty Race Muffler with 3-inch inlet and 3-inch outlet is engineered to maximize horsepower and torque for competitive racing applications. It is designed for environments where mufflers are required but sound restrictions or decibel limits are minimal, making it ideal for high-performance race vehicles.
Construction and Appearance. This muffler features a fully welded 16 gauge aluminized steel body for long-lasting durability. Its round shape allows easy installation in tight or limited-space areas. The finish is a high-temperature paint designed to withstand harsh operating conditions and maintain a clean appearance.
Installation. Installation requires basic exhaust system skills and may involve welding or clamp-on connections due to the slip-fit inlet and outlet design. This muffler is directional—the internal components are oriented toward the outlet—so proper positioning during installation is important. Some adaptation might be necessary to fit specific exhaust setups.
Application. Designed as a universal fit muffler, some adaptation is required for installation. It suits classic and late model muscle cars, as well as race vehicles.
