      Description

      Performance-Oriented Muffler. The Flowmaster 40 Series Delta Flow Offset/Offset Oval Muffler with 2.50-Inch inlet and 2.50-Inch outlet delivers aggressive sound with enhanced exhaust scavenging, designed for street, strip, and off-road applications. It provides a milder exterior tone with reduced interior resonance compared to standard 40 Series mufflers, improving overall driving enjoyment.

      Construction and Appearance. This muffler features rugged construction from 16 gauge aluminized steel, fully MIG welded for durability and longevity. It is finished with high-temperature black paint that offers resistance to heat and corrosion while maintaining a sleek, aggressive appearance.

      Installation. Installation is straightforward with slip-fit inlet and outlet connections designed for clamp-on or weld-on options. It requires new hangers, which are not included. Some adaptation may be necessary due to its universal fitment design, but no drilling is typically required.

      Application. Designed for universal fit with some adaptation required, this muffler suits a wide range of vehicles including 4 and 6-cylinder engines, classic and late model muscle cars, street rods, street/strip setups, and trucks/SUVs.
