About the Flowmaster 50 Series Big Block

Flowmaster’s 50 Series Big Block mufflers are built for large-displacement engines and vehicles that need substantial exhaust capacity while keeping sound levels controlled. The series uses a large body to provide more internal volume for sound management, making it particularly well suited to big-block muscle cars, trucks, SUVs, tow vehicles, motorhomes, and other applications with high exhaust volume. Flowmaster rates the 50 Big Block family with a mild-to-stock exterior exhaust tone and minimal interior resonance, so the goal is a deep performance character without the constant cabin presence of a more aggressive 40 Series or race muffler. Flowmaster also lists improved horsepower, torque, and engine efficiency among the intended benefits of the design. Several dual-inlet and dual-outlet configurations are available, which makes the series useful for combining or routing large exhaust systems through a single muffler body. The larger case does require more underbody room than a compact performance muffler, but that additional volume is what helps the 50 Series Big Block keep sound under control on powerful engines. For a large-cubic-inch street build, tow rig, heavy truck, or custom exhaust where strong flow and long-distance comfort are both important, the 50 Series Big Block provides a practical Flowmaster solution with a restrained exterior tone and reduced interior resonance.
