Upgrade your GM headers and keep the factory cats

These Torque Series headers give your GM V8 truck or SUV a stainless header upgrade using the OEM catalytic connection. The 1999-2001 version includes the EGR fitting, making that equipment choice part of the purchase from the start.

SKU: 28501110

Retain the OEM front connection

The 1-5/8" x 1-3/4" header tubing, round ports and stock bolt pattern suit the listed 4.8-, 5.3- and 6.0-litre applications. Flanged outlets bolt to the OEM catalytic converters.

Gaskets and bolts included

The fitting gaskets and bolt kit are supplied, with no additional connection parts required for the specified installation. You can upgrade the headers while retaining the rest of the factory front exhaust arrangement.

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.
