      Description

      Superior Performance. Dominate the streets or trails with the performance that these Stainless Works Factory Connect 1-7/8-Inch Catted Long Tube Headers are designed to provide. Their design allows for the exhaust to flow more freely and smoothly, which results in increased power. This way, you can drive with improved performance in intense driving situations.

      Improved Roar. The high-flow design of these Long Tube Headers provides unrestricted exhaust flow. This allows sound vibration to flow better and exit the vehicle with a more intimidating sound that guarantees to turn heads.

      High-Flow Cats. These Long Tube Headers feature high-flow catalytic converters. These are an excellent upgrade over your truck’s restrictive factory cats, giving you excellent performance in your most demanding drives.

      Durable Construction. These Long Tube Headers are built for maximum durability and lasting performance. They are made of highly durable 304 stainless steel that has been precision-designed and TIG-welded to ensure an excellent fit and lasting strength. They also feature a rust-resistant natural finish for an impressive style.

      Calibration Required. Setting up these Long Tube Headers will require tuning to reprogram your Sierra 2500 HD truck’s ECU for optimized performance. This allows you to enjoy the full potential of these high-performance headers.

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

          Word on the Trail

          Using paypal checkout was easy and quick. I really like the fact that all of the searches are tailored to find the items that will work with my truck, instead of having to look though a bunch of equipment I can not use.
