Header-Back Dual Exhaust Kit with Turbo Mufflers

The JEGS 555-30583 is a header-back dual exhaust kit engineered to provide improved exhaust flow and a distinctive sound. This kit includes turbo-style mufflers, which are known for producing a deep and aggressive exhaust note, and features mandrel-bent tubing. Mandrel bending ensures that the tubing maintains its diameter throughout the bends, preventing restrictions and maximizing exhaust gas velocity for better overall performance. Constructed from 409 stainless steel, this exhaust system is built for durability and resistance to corrosion. The kit is designed for a direct fit on specific GM models, including 1970-1981 GM F-Body vehicles and 1970-1974 GM X-Body vehicles. The 2-1/2 inch tubing diameter is optimized for performance applications. Installation typically involves placing the vehicle on a lift and test-fitting components to ensure proper alignment.
