Flowmaster Super 44 Series Exhaust Muffler

Turn up the attitude of your ride with the Flowmaster Super 44 exhaust muffler, a performance exhaust component engineered to deliver the most aggressive, deepest-sounding tone in Flowmaster’s four-inch case street muffler family. Built for enthusiasts who want their car exhaust to be heard, this muffler harnesses the same proven Delta Flow® technology found in the larger Super 40 mufflers, producing a powerful, rich tone paired with genuine street performance. Whether you’re building a weekend cruiser or a full-on street machine, this is a muffler that backs up its sound with substance.

Designed as a universal-fit unit, the Super 44 is a versatile choice when you shop for exhaust upgrades or piece together a custom exhaust system. It features a 2.50″ inlet diameter and a dual outlet location, making it a strong candidate for a wide range of exhaust automobile builds. With a compact 9.50″ body width, it fits neatly into tight chassis layouts common on classic muscle cars, letting you retain a purposeful, aggressive presence without excessive bulk.

Built to Last

Flowmaster constructs the Super 44 from 16-gauge aluminized steel and finishes it with high-temperature paint for durability under real-world heat and road conditions. Every seam is fully MIG welded for maximum strength, so this muffler is ready to handle the demands of a hard-driven performance exhaust setup. The aggressive sound level makes it a favorite among drivers who want their magnaflow muffler alternative to have real Flowmaster character behind it.

Key Highlights

  • Super 44 Series muffler with Delta Flow® technology for a powerful, rich, aggressive tone
  • 16-gauge aluminized steel construction, fully MIG welded for maximum durability
  • High-temperature paint finish to withstand heat and the elements
  • 2.50″ inlet diameter with a dual outlet location
  • Compact 9.50″ body width, ideal for classic muscle car chassis
  • Universal fitment for flexible custom exhaust system builds

Fitment & What to Know

This is a universal muffler intended for custom installation. It uses new hangers, which are not included, so plan your mounting hardware accordingly. Exhaust tips are also sold separately, giving you the freedom to finish the look of your cat back exhaust system or full exhaust build exactly the way you want. Because fitment is universal, confirm your pipe routing and inlet/outlet requirements before installation.

If you’re comparing mufflers and weighing a magnaflow exhaust or another catback exhaust option, the Flowmaster Super 44 stands out for enthusiasts chasing an unmistakably deep, aggressive note. It’s a smart centerpiece for any performance exhaust or cat back muffler system where sound, flow, and durability all matter. Add the Super 44 to your build and give your muscle car the voice it deserves.
