Description
Overview
The Flowmaster Super HP-2 Muffler in 304SS takes the proven laminar core of the classic HP-2 and reimagines it inside a new, compact square case. The result is the same trusted flow characteristics and moderate exhaust tone Flowmaster’s laminar-flow mufflers are known for, now delivered with sleeker, more modern styling that fits cleanly under a wide range of trucks and SUVs.
Built around a laminar flow design, the Super HP-2 Series is engineered to smooth out the exhaust path while producing a controlled, moderate sound level. That makes it an ideal choice if you want a noticeable upgrade in tone and performance feel without stepping into an aggressive, drone-heavy setup.

This version features a polishable 304 stainless steel (304SS) case, giving you a bright, finished look that stands up to the elements and can be polished to match a show-quality build. Across the Super HP-2 Series, Flowmaster offers case material options in both 409S and polishable 304S stainless steel, along with inlet sizing choices of 2.00 in., 2.25 in., and 2.50 in. — this configuration is set up with a 2.50 in. inlet diameter.

Fitment & Application

Please note the exhaust tip is sold separately, so you can pair the muffler with the tip style that best complements your build.
