Upgrade your HEMI headers while keeping the factory cats

These Kooks Super Street headers give your 6.4- or 6.2-litre HEMI car a stainless header upgrade that joins the OEM catalytic converters. The 1-7/8" primaries, factory bolt pattern and flanged outlets make this a different purchase route from a full long tube and connection-pipe conversion.

SKU: 31021400

Keep the OEM catalytic connection

D-shaped ports and EGR provisions form part of the header design. The collector outlets bolt directly to the factory cats, with no additional connection parts required for the specified installation.

Gaskets and bolts supplied

The headers include the fitting gaskets and bolt kit. A tune is not required as supplied, although we recommend tuning advice around your completed engine and exhaust modifications.

Fitting your exhaust

For the 6.4L installation, the supplied dipstick spacer and longer header bolt relocate the dipstick mounting point.

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.
