Description
Overview
The Flowmaster Super 44 Series Chambered Muffler brings big-muffler performance and unmistakable attitude to a compact four-inch case. Built around Flowmaster’s proven Delta Flow® technology — the same design found in the larger Super 40 mufflers — the Super 44 is engineered to deliver a rich, powerful tone with the kind of aggressive character muscle car owners crave. Flowmaster describes it as the most aggressive, highest-performing street muffler they’ve ever built in a four-inch case, making it a standout choice for drivers who want serious sound without sacrificing everyday street manners.
Built to Last
Durability is baked into every seam. The Super 44 is constructed from 16-gauge 409S stainless steel and fully MIG welded for maximum strength and long service life under demanding conditions. A high-temperature paint finish helps the housing stand up to the heat of continuous exhaust duty, so the muffler looks and performs the part mile after mile.
Sound & Performance
If you’re chasing that classic, deep Flowmaster growl, the Super 44 answers with an aggressive sound profile tuned for late-model muscle cars. Delta Flow technology directs and manages exhaust pulses through a chambered design, producing a bold exhaust note while promoting strong flow — the perfect blend of tone and street-friendly performance in a slim, easy-to-package body.
Fitment & Installation
This is a universal-fit muffler with a 3.00-inch inlet diameter and a 9.50-inch body width, giving you the flexibility to integrate it into a wide range of custom and replacement exhaust builds. Because it uses new hangers (not included), you can position and secure the muffler exactly where your application requires. Plan your build accordingly: exhaust tips are sold separately, so you can finish the system with the look you want.
