The Flowmaster 50 Series is designed to reduce the interior sound and resonance without sacrificing a good exterior tone level. This is ideal for those who seek a quiet interior for their vehicle.

The Delta Flow muffler is a milder version out of the other Flowmaster mufflers. It produces a mellow and deep sound. With a quiet interior, you can expect a more mellow exterior tone as well with this.

Thanks to the Delta Flow technology, you will get superb performance out of this muffler as well. It is designed to increase your vehicle’s horsepower and torque.

This 3-chamber muffler will deliver to you the same performance as the 2-chambered Flowmaster mufflers today. The only difference is, with the 50 series, you get better energy efficiency and mileage!
