Flowmaster Super 44 muffler uses the same delta flow technology found In our larger Super 40 mufflers. The Super 44 delivers a powerful rich tone and is the most aggressive, deepest soundIng, highest performIng four Inch case street muffler Flowmaster has ever built. Constructed of 16 gauge alumInized steel and fully MIG welded for maximum durability.
- DEEPEST, MOST AGGRESSIVE TWO-CHAMBER SOUND: Built as the next evolution of the 40 Series, the Super 44 features an additional internal chamber with both chambers sized and spaced differently. This design delivers a deeper tone, improved performance, and aggressive exterior sound level, while offering moderate interior resonance.
- TWO-CHAMBERED INTERNAL DESIGN: Engineered with Flowmaster’s Delta Flow dual-chamber technology, the Super 44’s two-chamber configuration improves scavenging, enhances power and torque, boosts throttle response, and helps reduce interior resonance.
- PROVEN PERFORMANCE: Enhances airflow and exhaust efficiency for better throttle response, acceleration, and all-around street performance across the RPM range.
- BUILT TO LAST: Constructed from 16-gauge aluminized steel and fully MIG-welded for durability under high heat, vibration, and aggressive driving conditions.
- UNIVERSAL FITMENT: Compact 4-inch case works in tighter clearances where bigger mufflers won’t fit. Ideal for muscle cars, trucks, off-road rigs, hot rods, lowered customs, and street/strip builds and daily drivers that want to stand out. Available in multiple inlet/outlet options to support custom builds and modified vehicles. Main case dimensions: 13” length x 9.5” width x 4.0” thick.
