Description
Overview
The Flowmaster Super HP-2 Muffler in 409SS takes the proven laminar core of the classic HP-2 muffler and wraps it in a new, compact square case. The result is the same performance-minded flow and moderate exhaust tone Flowmaster’s laminar flow mufflers are known for, now delivered in a sleeker, more modern package. If you want a refined upgrade that improves the character of your exhaust without an aggressive drone, the Super HP-2 Series is built to hit that balance.
This configuration features a durable 409 stainless steel case finished in high-temperature paint, giving it the heat resistance and corrosion protection needed to stand up to real exhaust conditions mile after mile. With a 2.25 in. inlet diameter and a compact 5.00 in. body width, it’s designed to tuck neatly into a wide range of exhaust routing while still delivering the flow benefits of the laminar core inside.
Key Benefits
The Super HP-2 is engineered specifically for smaller-displacement engines, making it an ideal match for 4- and 6-cylinder applications. Its laminar flow design promotes smooth exhaust movement while producing a moderate sound level — loud enough to add presence, but controlled enough for comfortable daily driving. The redesigned square case not only looks clean underneath the vehicle but also keeps the overall footprint tight.
