Keep your factory cats and upgrade the HEMI headers
These Kooks Super Street headers give your 5.7-litre HEMI car a stainless header upgrade with the OEM catalytic connection retained. You get 1-7/8" primaries, D-shaped ports and the stock bolt pattern, with fitting gaskets and bolts included.
SKU: 31001400
Direct connection to the OEM cats
The flanged collector outlets connect to the factory catalytic converters. EGR provisions are included, and the specified installation needs no additional connection parts.
A simpler route than a full long tube conversion
Keeping the factory cats avoids buying the separate front connections used by Kooks long tube headers. A tune is not required as supplied; we recommend tuning advice for your finished engine and exhaust setup.
Fitting your exhaust
The fitting pack includes a dipstick spacer. Installation relocates the dipstick mounting point using this spacer and the longer header bolt.
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.
