Description
Overview
The Flowmaster Super 44 Series Exhaust Muffler is built for enthusiasts who want a rich, powerful tone and serious street performance from their car exhaust. Using the same proven Delta Flow® technology found in Flowmaster’s larger Super 40 mufflers, the Super 44 packs that aggressive character into a compact four-inch case. Flowmaster calls it the most aggressive, highest-performing street muffler they’ve ever built in a four-inch design, making it a standout choice when you shop for exhaust upgrades.
Whether you’re chasing a deeper note on a daily driver or completing a full performance exhaust build, this MagnaFlow-caliber-class Flowmaster muffler brings the loud, unmistakable sound that muscle car owners crave. It’s engineered as part of a broader exhaust system strategy, letting you pair it with the piping and tips that suit your setup.
Construction & Durability
This muffler is constructed of 16-gauge 409S stainless steel and fully MIG welded for maximum durability, so it holds up to the heat, vibration, and road abuse that come with real-world driving. A high-temperature paint finish adds an extra layer of protection against the elements, helping the muffler look and perform its best mile after mile.
