Description
Unlock the full potential of your 2020–2023 Silverado HD or Sierra HD 6.6L gas engine with the Stainless Works 1-7/8" Long Tube Header Kit – Performance Connect. Designed for performance enthusiasts who demand aggressive sound and increased horsepower, this header system transforms your truck into a more powerful and exhilarating machine.
These 1-7/8” mandrel-bent primaries flow into 3” collectors with integrated merge spikes, optimizing exhaust velocity for maximum performance gains. High flow catalytic converters further enhance exhaust flow, while the included Y-pipe allows for a bolt-on upgrade that maintains smooth drivability and power delivery.
The Performance Connect configuration is designed to pair directly with Stainless Works Redline or Legend cat-back systems, creating a full true dual exhaust system that significantly improves tone and efficiency over factory components. Whether you're towing, cruising, or hitting the throttle, this system delivers consistent power and bold sound without compromise.
Crafted from premium 304 stainless steel and TIG welded in the USA, these headers are built to withstand extreme conditions while maintaining corrosion resistance and structural integrity. Backed by a limited lifetime warranty, this system offers peace of mind and performance you can trust.
