Overview
The Flowmaster 40 Series Delta Flow Exhaust Muffler brings proven performance and an unmistakable aggressive tone to your build. Engineered with a two-chamber design and Flowmaster’s Delta Flow® technology, this muffler is built for Street/Strip vehicles that demand real power gains and a purposeful sound. As a universal-fit performance muffler, it slots into a wide range of custom exhaust setups, making it a smart foundation for any car exhaust or catback exhaust project.
Delta Flow® Performance
At the heart of this muffler are Flowmaster’s Delta deflectors, which generate increased scavenging for better performance and reduced interior sound. The result is a milder exterior tone and reduced interior resonance compared to the standard 40 Series, so you get the aggressive character you want without unwanted drone inside the cabin. Whether you’re upgrading a daily driver or assembling a dedicated cat back exhaust system, the 40 Series Delta Flow delivers the balance of power and volume that performance enthusiasts look for in a magnaflow muffler alternative.
Built to Last
This Flowmaster muffler is constructed of 16 gauge aluminized steel and fully MIG welded for maximum durability. A high-temperature paint finish helps it stand up to the heat and demands of a performance exhaust system, mile after mile. When you shop for exhaust components that need to survive both the street and the strip, this rugged construction earns its place in your exhaust system.
