Description
Transform your truck into a statement of raw power and refined engineering with the Stainless Works Redline Cat-Back Exhaust System for the 2020–2023 Chevrolet Silverado HD and GMC Sierra HD 6.6L Gas. Crafted for drivers who crave volume and aggression, the Redline system is tuned to unleash a bold, throaty exhaust note while eliminating cabin drone for a balanced driving experience.
This 3" high-performance system includes dual chambered mufflers and aggressive 4" matte black slash-cut double-wall tips. Designed to deliver both powerful sound and standout aesthetics, this exhaust system is perfect for those who demand performance without compromise.
The system includes a Y-pipe for easy bolt-on installation to the factory exhaust manifolds or can be configured without the Y-pipe for use with Stainless Works Long Tube Headers, converting it into a true dual setup for maximum flow and horsepower gains.
Precision-crafted from 304 stainless steel and TIG-welded in Stainless Works’ state-of-the-art Ohio facility, this system resists corrosion and delivers long-lasting durability. With a lifetime warranty on materials and craftsmanship, you can count on this system to perform for years to come.
