Description
Overview
The Flowmaster Exhaust Muffler brings proven Delta Flow® performance to your build with the popular 50 Series Delta Flow design. Engineered for the enthusiast who wants a strong, refined exhaust note without excessive cabin drone, this muffler pairs a moderate sound level with the durability you expect from a name that has defined performance exhaust for generations. Whether you’re refreshing a tired system or planning a full exhaust system upgrade, this is the kind of muffler that anchors the job.
At the heart of this design is a three-chamber layout that combines Flowmaster’s Delta Flow® technology with an internal tuning chamber. That extra chamber is the key difference: it works to reduce sound inside the vehicle while delivering the same performance and exterior tone characteristics as the two-chamber version. The result is a Flowmaster muffler that keeps the aggressive exterior character owners love while cutting down on interior resonance for a more comfortable drive.
Built to Last
Construction is all business. The body is formed from 16 gauge aluminized steel and fully MIG welded for maximum durability, then protected with a high-temperature paint finish to stand up to the heat and elements that come with any car exhaust environment. It’s a straightforward, rugged package designed to serve as the core of a dependable exhaust automobile setup.
