Overview
The Flowmaster Exhaust Muffler brings proven performance and unmistakable street presence to your build. Part of the acclaimed 40 Series Delta Flow lineup, this muffler features a two-chamber design that incorporates Flowmaster’s Delta Flow® technology. The Delta deflectors are engineered to generate increased scavenging for better performance while simultaneously reducing interior sound, making it a smart upgrade for anyone shopping for exhaust that delivers both power and refinement.
Whether you’re piecing together a complete exhaust system or replacing a tired muffler, this Flowmaster muffler is built to perform. As a Street/Strip-rated component, it strikes the balance between an aggressive sound level and everyday drivability, giving your car exhaust that deep, purposeful tone without overwhelming resonance inside the cabin.
Key Benefits

The Delta deflectors improve exhaust flow and scavenging, contributing to stronger performance from your exhaust automobile setup.
Durability is built into every detail. Constructed of 16 gauge aluminized steel and fully MIG welded, this Flowmaster muffler is made to withstand the heat and vibration of demanding street and strip use. A high-temperature paint finish helps protect the housing against the elements over the long haul.
