Race-Ready Performance. The Flowmaster Outlaw Series Center/Center Race Muffler with 2.50-Inch Inlet and 2.50-Inch Outlet diameters, measuring 17 inches in length, delivers an aggressive sound and optimized exhaust flow tailored for racing applications. It is engineered for direct installation on header collectors or integration into existing exhaust systems requiring mufflers where no decibel limits are enforced. This muffler improves performance while maintaining emissions compliance for specified vehicle applications.
Construction and Appearance. Made from durable 409 stainless steel, this muffler features mandrel bent 16 gauge tubing to ensure precise flow and enhanced durability. It is coated with a high-temperature black paint finish that resists heat and corrosion. The round reflection-type design contributes to its aggressive sound profile while preserving structural integrity.
Installation. Installation generally requires some adaptation due to its universal fitment. The muffler features slip-fit clamp-on connections but does not include clamps or hangers. Basic mechanical skills are recommended, and minor modifications may be necessary to properly integrate it into different exhaust configurations.
Application. Designed with universal fitment in mind, this muffler requires some adaptation during installation and is ideal for classic muscle cars, late model muscle cars, and race vehicles where noise restrictions do not apply. It is directional and must be installed with correct orientation of inlet and outlet according to the internal ring design to ensure proper function.
