Overview

The Flowmaster Super 44 Series Chambered Muffler is engineered for enthusiasts who want a rich, powerful, and aggressive exhaust note without sacrificing street performance. Built around Flowmaster’s proven Delta Flow® technology—the same design found in the larger Super 40 mufflers—the Super 44 packs serious performance into a compact four-inch case, making it one of the most aggressive, highest-performing street mufflers Flowmaster has ever produced.

Designed as a universal-fit chambered muffler, the Super 44 is a natural upgrade for late model muscle cars and any build that demands a bold, unmistakable sound. Its dual inlet and dual outlet configuration with a 2.50-inch inlet diameter helps deliver smooth flow while producing that signature Flowmaster tone.

Built to Last

Durability is at the core of the Super 44’s construction. Each muffler is made from 16-gauge 409S stainless steel and fully MIG welded for maximum strength and long-term reliability, standing up to the heat and demands of aggressive street driving. A high-temperature paint finish adds an extra layer of protection to keep the muffler looking and performing its best.

Sound & Performance

If you’re chasing an aggressive sound level with a deep, throaty character, the Super 44 delivers. The Delta Flow® technology inside the chambered design produces a rich, powerful tone that announces your build before it comes into view—while maintaining the performance-minded flow Flowmaster is known for.
