Description
Overview
The Flowmaster Exhaust Muffler brings proven Delta Flow® performance and a refined, moderate tone to your build. Part of the acclaimed 50 Series Delta Flow lineup, this muffler is engineered around a three chamber design that layers Flowmaster’s Delta Flow® technology with an internal tuning chamber, delivering strong flow while noticeably calming the sound inside the cabin. If you’ve been looking to shop for exhaust that balances power and comfort, this performance exhaust muffler is built for drivers who want serious airflow without a punishing drone on the highway.
Compared to a two chamber design, this three chamber muffler provides the same performance and exterior tone characteristics but with less interior resonance. That makes it an ideal centerpiece for a car exhaust upgrade on a classic muscle car, where you want an aggressive presence outside and a livable, moderate sound level behind the wheel.
Built to Last
Durability is engineered in from the inside out. The body is constructed of 16 gauge aluminized steel and fully MIG welded for maximum strength, then finished with high-temperature paint to help stand up to the heat and demands of a working exhaust system. With a 9.75″ body width and a 3.00″ inlet diameter, this Flowmaster muffler is designed to move air and hold up mile after mile.
