Keep the factory cats with a stainless header upgrade

Upgrade the headers on your GM V8 truck or SUV while keeping its OEM catalytic connection. This 2002-2013 Torque Series version comes without an EGR fitting and includes the gaskets and bolt kit for the specified installation.

SKU: 28501120

The no-EGR configuration

The 1-5/8" x 1-3/4" header tubing uses round ports and the stock bolt pattern. The application includes the 4.8-, 5.3-, 6.0- and 6.2-litre models listed below.

Retain the factory front exhaust route

Flanged collector outlets connect directly to the OEM cats, so a separate long tube Y-pipe is not part of this installation. No additional connection parts are required as specified.

Tuning for your exhaust upgrade

We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Talk to us to discuss the right tuning route for your vehicle.
