Review FLOWMASTER Holley fits SILVERADO SIERRA 2014–2018

The Flowmaster 717869 exhaust system is a high-performance upgrade for select 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 5.3L CBD (Crew Cab Short Bed) models. This system, developed in collaboration with Holley, is designed to deliver an exceptional balance of power and sound.

At its core is a 1 -inch inlet and 2 -inch outlet mandrel-bent stainless steel exhaust system. The use of mandrel bends ensures minimal restriction and maximum flow, allowing the engine to breathe more efficiently. The system features a straight-through design, which reduces backpressure, and enhances engine performance.

The exhaust system comes with a set of 409S series mufflers. These mufflers use a unique internal design that provides a deep, rumbling exhaust note without being overly loud or intrusive. The mufflers are coated with a high-temperature ceramic coating that protects them from the extreme heat generated by the exhaust gases. Additionally, the ceramic coating helps to reduce under-hood temperatures, contributing to a cooler engine compartment.

Mounting the exhaust system is made simple with the use of factory-style hangers and OEM-style mounting points. This ensures a secure and stable installation that retains the factory-like fit and finish. The system also comes with all necessary hardware and clamps for installation.

The Flowmaster 717869 exhaust system is a direct replacement for the factory exhaust system, making it a straightforward upgrade. It is designed to work seamlessly with the factory catalytic converters, ensuring compliance with emissions regulations. The system is also CARB (California Air Resources Board) and 50-state legal, allowing it to be used in all areas of the United States.

In summary, the Flowmaster 717869 exhaust system is a high-quality, performance-enhancing upgrade for select 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 5.3L CBD models. It delivers a deep exhaust note, improved engine performance, and a secure, factory-like installation. The system is made from mandrel-bent stainless steel, features OEM-style mounting points, and is CARB and 50-state legal.
