Advanced Delta Flow technology enhances performance and sound control.
The Flowmaster Exhaust Muffler 40 Series Delta Flow features a two chamber design that utilizes advanced Delta Flow technology. This innovative design incorporates deflectors that enhance exhaust scavenging, resulting in improved performance while minimizing interior sound levels. The muffler produces a milder exterior tone and reduces interior resonance compared to standard 40 series models, making it suitable for various applications.
Constructed from durable 16 gauge aluminized steel, this muffler is fully MIG welded to ensure maximum durability and longevity. It is designed for both street and strip use, as well as off-road applications, providing versatility for different driving conditions. The absence of internal packing eliminates the risk of blowout, ensuring consistent performance over time.
With a center single inlet of 3 inches and dual 2-1/4 inch outlets, this muffler is engineered for vehicle-specific applications. Its dimensions include a case diameter of 9-3/4 inches by 4 inches, a body length of 13 inches, and an overall length of 19 inches. Installation may require modifications to the exhaust system, and the estimated installation time is approximately one hour.
