About the Flowmaster 40 Series Delta Flow

Flowmaster’s 40 Series Delta Flow combines the aggressive personality of the 40 Series family with race-proven Delta Flow technology intended to improve exhaust pulse control and overall performance. The design is built for street/strip, off-road, muscle-car, truck, and custom applications where a strong exterior exhaust note is desired. Flowmaster uses fully welded construction and no internal packing material, so there is no conventional sound-absorbing fill to deteriorate or blow out over time. Depending on the specific part number, the muffler may use aluminized steel or 409 stainless-steel construction. The oval case is available with a wide range of inlet and outlet arrangements, including center, offset, dual-outlet, and other configurations that make the series easy to integrate into custom exhaust routing. Compared with Flowmaster’s milder 50 and 70 Series mufflers, the 40 Series Delta Flow is intended to sound more assertive and performance focused. It is therefore a good match for enthusiasts who want the exhaust to be clearly audible during acceleration and cruising. The combination of durable welded construction, Delta Flow technology, and flexible configurations makes the series a long-standing choice for street machines and performance trucks. For a build that needs classic Flowmaster aggression with a refined Delta Flow chamber design, the 40 Series Delta Flow provides a proven, versatile muffler platform.
