40 Series Delta Flow Stainless Steel Muffler

The Flowmaster 40 Series Delta Flow muffler represents a refinement of the classic two-chambered design, offering a more subdued sound profile while retaining signature Flowmaster performance. It is engineered to provide reduced resonance compared to its predecessors, making it a quieter choice within the popular 40 Series lineup. Constructed from robust 409SS stainless steel, this muffler is built for longevity and resistance to corrosion. The Delta Flow technology optimizes exhaust gas flow for improved performance and sound. This muffler is part of Flowmaster's extensive range of performance exhaust components. Flowmaster offers a wide selection of mufflers, and fitment can vary significantly based on the specific vehicle's make, year, and model. For optimal results and to ensure proper integration, it is recommended to consult Flowmaster's official fitment guides or select your vehicle details on their website to confirm compatibility. The "40 Series" designation indicates a particular sound profile and performance characteristic, and the "Delta Flow" variant aims to temper the aggressive tone associated with some other 40 Series mufflers. Generally, in full-size vehicle applications, a 5-7% gain in power can be expected with performance exhaust modifications like this muffler.
