Description

Flowmaster 50 Series Delta Flow mufflers are designed to produce a mellow, deep sound. They're milder on the outside of the vehicle than the 40 Series mufflers and are significantly quieter on the inside. These mufflers combine the increased horsepower and torque you've come to expect from Delta Flow technology with the performance sound and feel that makes Flowmaster famous.
