Description
Overview
The Flowmaster Flow FX Exhaust Muffler is engineered for the enthusiast who wants a moderate, refined performance tone that stands apart from the traditional “chambered” muffler sound. Built with a dual 3.00-inch inlet and dual 3.00-inch outlet, this muffler is a natural fit for large displacement gas engines that need a free-flowing path and a deeper, more traditional exhaust note. Whether you’re upgrading a tired factory setup or building out a complete performance exhaust system, the Flow FX delivers show-quality looks and a mellow, purposeful sound.
At the heart of this Flowmaster muffler is a large 3.00-inch “straight-through” X-pipe style stainless steel perforated core. That core is wrapped in high-temperature sound absorption materials to tame harshness and produce a deep, traditional mellow tone at a moderate sound level. The internal flow design is fully reversible, so the muffler can be installed in either direction to best suit your vehicle application and routing.
Built to Last, Built to Show
Construction is fully MIG-welded from “bright” 409 stainless steel for durability and a clean, finished appearance under the vehicle. The Flow FX logo is embossed on both sides of the case, giving this car exhaust component the kind of detail that looks as good as it sounds. The compact case size makes it a versatile choice when packaging space is tight, and its economical price point makes stepping up to a genuine Flowmaster muffler an easy decision.
