Description
The Flowmaster Super 44 Series® Stainless Steel Chambered Muffler is engineered for enthusiasts who demand an aggressive exhaust tone and maximum street performance. Utilizing the same race-proven Delta Flow® technology found in Flowmaster’s larger Super 40 Series mufflers, the Super 44 delivers a rich, powerful exhaust note and represents one of the most aggressive, highest-performing four-inch case street mufflers Flowmaster has ever produced.
Featuring a recent two-chamber internal design improvement, this muffler produces a deep, aggressive exhaust sound with noticeable interior resonance, making it ideal for performance-focused builds. Constructed from durable 16-gauge 409 stainless steel and fully MIG welded, the Super 44 Series offers excellent strength, corrosion resistance, and long-term durability in demanding driving conditions.
Its compact oval body allows for versatile installation in custom exhaust systems while maintaining exceptional exhaust scavenging and throttle response.
