Description
The Flowmaster Super HP-2 Series Muffler combines classic laminar flow performance with a modern compact design. By taking the proven laminar core from Flowmaster’s original HP-2 muffler and housing it in a sleek square-style case, the Super HP-2 delivers excellent exhaust flow, improved performance, and a refined moderate exhaust tone.
Constructed from 409 stainless steel and finished with a high-temperature black coating, this muffler is dyno-tuned to maximize performance while maintaining smooth, controlled sound levels. The laminar flow internal design reduces restriction, making it an ideal choice for street-driven performance vehicles that require balanced sound and efficiency.
