      Description

      Product Overview. The Flowmaster 40 Series Delta Flow Offset/Dual Out Oval Muffler; 3-Inch Inlet/2.25-Inch Outlet is engineered to improve exhaust flow and produce an aggressive sound suitable for street and strip applications. Featuring a two-chamber design with Delta Flow® technology, it enhances scavenging to boost performance while reducing interior resonance for a more enjoyable driving experience.

      Construction and Appearance. Crafted from durable 16 gauge aluminized steel with fully MIG welded seams, this muffler ensures maximum strength and longevity. The high-temperature black paint finish provides corrosion resistance and a sleek look even under extreme conditions.

      Installation. Installation requires basic mechanical skills with no mandatory drilling. The muffler uses slip-fit inlet and outlet connections that support clamp-on or weld-on methods, enabling a secure and adaptable fit.

      Application. Designed as a universal fit muffler, some adaptation may be necessary depending on the vehicle’s exhaust configuration and setup.
