Description
Overview
The Flowmaster 40 Series Delta Force race muffler is a purpose-built performance exhaust muffler engineered for competition machines that demand serious power and a genuinely aggressive tone. Built around Flowmaster’s proven Delta Flow technology, this muffler delivers excellent power characteristics while still providing meaningful sound reduction — making it Flowmaster’s recommendation for racing applications that require a muffler with a substantial decibel reduction over open headers. If you’re ready to shop for exhaust hardware that can back up its bark, the Delta Force 40 Series belongs on your short list.
As part of the Flowmaster mufflers family, this cornerstone of a performance exhaust system pairs a race-focused character with real-world drivability at the track. The 40 Series Delta Force name has become synonymous with an unmistakable, aggressive sound level, and this muffler carries that reputation forward while managing volume better than open headers.
Key Benefits
The core of this magnaflow-alternative Flowmaster muffler is its Delta Flow internal design, which is what gives the 40 Series its strong power delivery and distinctive tone. A 3.50-inch inlet diameter provides generous flow for higher-output builds, and the high-temperature paint finish is chosen to stand up to the heat this component sees in hard use. Whether you’re refreshing your car exhaust or building an exhaust system from the ground up, this muffler is a proven, race-oriented centerpiece.
