Performance Muffler. The Flowmaster Original 40 Series Offset/Center Oval Muffler with 2.50-Inch Inlet and 2.50-Inch Outlet is engineered to deliver an aggressive exterior exhaust tone with deep sound characteristics. It is ideal for street, strip, and off-road applications where a distinctive, powerful sound is desired alongside robust muffler performance.

The body features a high-temperature black painted finish that enhances durability and adds a sleek appearance suitable for performance-oriented vehicles.
Installation. Installation is straightforward with slip-fit inlet and outlet connections that allow easy clamp-on or weld-on attachment. The muffler requires new hangers, which are not included, and clamps must be sourced separately.

Designed as a universal fitment muffler, it fits a wide range of vehicle types including classic and late model muscle cars, street rods, street/strip vehicles, and trucks/SUVs. Some adaptation may be required to ensure proper fitment depending on specific vehicle configurations.
