      Description

      Aggressive Performance Muffler. The Flowmaster 80 Series Offset/Offset Same-Side-Out Oval Muffler; 2.50 Inlet/2.50 Outlet delivers a powerful and muscular exhaust tone designed for classic and late-model muscle cars. It enhances both exterior and interior exhaust sound with a distinctive aggressive tone, suitable for street and strip applications where a side exit exhaust is desired. The muffler is ideal for installations in front of the rear axle, replicating the classic side exit style found on iconic muscle cars.

      Construction and Appearance. Constructed from durable 16 gauge aluminized steel, this muffler features a fully MIG-welded assembly for enhanced longevity and strength. It is finished with a high-temperature resistant black paint coating that provides a sleek look while protecting against rust and corrosion. The oval-shaped muffler has a crossflow, chambered transverse design to optimize exhaust flow and sound quality.

      Installation. Installation requires moderate mechanical skill, with a universal fitment that may necessitate some adaptation to the vehicle’s specific exhaust system layout. No additional drilling is usually needed as this muffler uses slip-fit inlet and outlet connections compatible with clamp-on or weld-on methods.

      Application. Fits universally with some adaptation; this muffler is designed for classic and late-model muscle cars as well as street and strip use, accommodating side exit systems mounted ahead of the rear axle. No specific vehicle exclusions are noted, making it versatile for custom exhaust builds.
