About the Flowmaster FlowFX

Flowmaster’s FlowFX series is built around a high-flow straight-through design for drivers who want a clean, modern performance tone with less of the sharp chambered character found in many traditional Flowmaster mufflers. The series uses durable fully welded stainless-steel construction, with many models featuring a bright 409 stainless case designed for long service life and a clean appearance. Flowmaster rates the FlowFX family with a moderate exterior performance tone, while certain configurations use high-temperature interior sound-absorption material to keep the cabin tone in the mild-to-moderate range. The straight-through internal path is intended to support strong exhaust flow and makes the series a versatile option for naturally aspirated, turbocharged, and custom exhaust systems. FlowFX mufflers are offered in several body styles and inlet/outlet configurations, including compact round cases, oval cases, transverse layouts, dual outlets, and direct-fit truck applications. Universal versions give fabricators flexibility for custom routing, while direct-fit versions are engineered to use factory hanger locations and simplify installation on the intended vehicle. For a street car, truck, import, muscle car, or custom project that needs stainless durability and a noticeable but manageable performance sound, FlowFX provides a modern Flowmaster option focused on efficient flow, straightforward packaging, and everyday usability.
