Improve exhaust performance and sound with the Flowmaster Super HP-2 Muffler, engineered with a compact square case for modern styling and excellent flow characteristics. Built around Flowmaster’s proven laminar core technology, this muffler delivers a moderate, refined performance tone while optimizing exhaust velocity for improved throttle response and efficiency.

The Super HP-2 features a durable 409 stainless steel case, fully designed for long-lasting performance under high-heat conditions. It offers the same performance benefits of the original HP-2 design but in a sleeker, space-saving shape ideal for tight clearance applications.

With a 2.50-inch center inlet and outlet, slip-fit connections, and a moderately aggressive but controlled sound profile, this muffler is designed for drivers seeking better performance without excessive interior noise.
