Constructed of 16 gauge aluminized steel and fully MIG welded for maximum durability.

Product Features

• 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.
