      Description

      Distinctive Flowmaster Sound. The Flowmaster American Thunder Cat-Back Exhaust is designed to deliver a distinctive powerful exterior sound level while keeping the interior sound level moderate. Utilizing their patented Delta Flow technology, Flowmaster is able to calibrate the interior and exterior sound levels. This means that you can still turn heads with your Silverado’s attention-grabbing growls and still enjoy a comfortable ride with reduced sound levels inside the cab.

      Improved Performance. Another benefit of Flowmaster’s Delta Flow technology is the improved scavenging design. By combining this with the mandrel-bent tubing’s smoother exhaust flow, the kit is able to significantly improve the Silverado’s performance.

      High-Quality Stainless Steel Construction. The American Thunder is made from high-grade stainless steel to give it outstanding durability and longevity. Precision-machined mandrel-bent tubing provides the smoothest airflow possible while delivering the desired sound levels.

      Designed for Easy Fit. The American Thunder Cat-Back Exhaust is designed to make the installation process as simple as possible. It comes with the optional parts for either dual side or dual rear exit configuration. Flowmaster recommends welding all slip-fit connections for a more secure installation.

      Application. The Flowmaster American Thunder Cat-Back Exhaust with split side or rear exits is designed to fit 2014 to 2018 4.3L Chevy Silverado 1500 models equipped with Double or Crew Cabs. It’s not compatible with 2WD Crew Cab models with 2-piece driveshaft.
