Upgrade your vehicle’s exhaust system with the Flowmaster Super 40 Series Muffler, part number 953045. Designed with Flowmaster’s race-proven Delta Flow technology, this universal muffler delivers the deep, powerful exhaust note associated with the Original 40 Series while helping reduce interior resonance. Its larger case profile balances aggressive sound with practical street performance, making it a strong choice for high-horsepower applications and custom exhaust projects.

Constructed from durable 16-gauge aluminized steel, the Super 40 is fully MIG welded for long-lasting strength and reliable performance under demanding driving conditions. The center inlet and center outlet configuration provides installation flexibility for a variety of exhaust layouts. Because this is a universal muffler, some adaptation, fabrication, or additional exhaust components may be required for proper installation on your vehicle.

The Flowmaster Super 40 is engineered to provide an aggressive exterior exhaust tone with moderate interior resonance. Its Delta Flow technology helps manage sound and exhaust flow while maintaining the bold character expected from a performance muffler. This model is suitable for select 1999–2003 Ford F-250 Super Duty applications when used with a compatible custom or replacement exhaust system. Verify vehicle configuration, exhaust routing, and available installation space before ordering.
