Bring the original Flowmaster sound to your custom exhaust system with the Flowmaster 40 Series stainless steel universal muffler. Designed for drivers who want an aggressive exterior tone and noticeable interior resonance, this muffler is well suited for street, strip, and off-road applications. Its proven 40 Series design delivers the bold exhaust character associated with Flowmaster while providing a durable solution for a wide range of performance-oriented builds.

Constructed from 16-gauge 409S stainless steel, the Flowmaster 8043041 is built to withstand the demands of daily driving, spirited use, and off-road conditions. Fully MIG-welded construction helps reinforce the muffler for long-term durability and dependable performance. The stainless steel body also provides strong resistance to corrosion, making it a practical choice for custom exhaust systems exposed to changing weather and road conditions. The offset inlet and center outlet layout supports flexible installation where the exhaust system requires a specific flow path.

This universal muffler is intended for custom installation, and some adaptation may be required to accommodate the vehicle’s existing exhaust routing, hangers, and pipe configuration. It can be used on a variety of applications, including select Ford Expedition, Ford F-250, and Ford F-250 Super Duty models, when the vehicle’s exhaust configuration is compatible. Verify clearance, inlet and outlet positioning, and installation requirements before purchase.
