      Upgraded Performance. Outperform the vehicles on the roads or tails with the performance that these Stainless Works Performance 1-7/8-Inch Catted Long Tube Headers are engineered to deliver. Their design promotes excellent exhaust flow, resulting in increased power, so you can drive with remarkable performance anywhere.

      Impressive Racing Sound. The high-flow design of these Long Tube Headers delivers unrestricted exhaust flow. As such, they allow sound vibration to flow and exit the vehicle more freely, producing an intimidating sound that never fails to draw attention.

      High-Performance Cats. These Long Tube Headers are equipped with high-flow catalytic converters. They are designed to perform better than your truck’s restrictive OE cats, giving you remarkable performance in high-intensity driving conditions.

      Heavy-Duty Quality. These Long Tube Headers are designed for years of durability and reliable performance. They are made of heavy-duty 304 stainless steel with a rust-proof natural finish. They are precision-designed and TIG-welded to guarantee a perfect fit and lasting strength.

      Calibration Required. Setting up these Long Tube Headers requires calibration to reprogram your Sierra 2500 HD truck’s ECU to guarantee optimized performance. This lets you take advantage of the full potential of these high-performance headers.

      Application. These Stainless Works Performance Connect 1-7/8-Inch Catted Long Tube Headers is designed to fit all 2020-2025 6.6L Gas GMC Sierra 2500 HD models.
