Description
Overview
The Flowmaster Super HP-2 Muffler in 304SS takes the proven laminar core of the classic HP-2 and wraps it in a new, compact square case for a sleeker, more modern look under your vehicle. Built to deliver the same performance benefits and moderate tone Flowmaster’s laminar flow mufflers are known for, the Super HP-2 blends refined styling with the aggressive sound street and strip enthusiasts crave.
This version features a polishable 304 stainless steel case, giving you the durability of premium stainless along with the option to bring the exterior to a bright, show-quality shine. It’s part of Flowmaster’s HP-2 Series and is proudly manufactured in the USA.
Sound & Performance
The laminar core is engineered to promote smooth exhaust flow while producing an aggressive yet moderate tone — assertive enough to make a statement without droning. That balance makes the Super HP-2 an ideal match for a wide range of street and strip builds, whether you’re chasing better throttle response or simply a more purposeful exhaust note.
Fitment & Configuration
This muffler is a universal-fit design with a 2.50 in. inlet diameter, making it a flexible choice for custom exhaust fabrication and upgrade projects. Its compact square case helps it tuck neatly into tight chassis spaces where a traditional round body might not fit. Exhaust tips are sold separately, so you can tailor the finished look to match your setup.
