Make more of your Hellcat with a matched Kooks upgrade

Pair 2" Kooks long tube headers with GREEN catted front connections for your supercharged Charger or Challenger Hellcat. The kit joins the 2-3/4" OEM rear interface, giving you a matched front system while leaving your favourite rear exhaust in place.

SKU: 3103H630

A complete header-and-connection purchase

The 2" primary tubing leads into 3" collectors and the supplied GREEN pipes. The 2-3/4" rear outlet is the factory-style connection for this package. Choose the kit around the rear exhaust you are actually using, especially if it has been changed before.

GREEN cats for your supercharged HEMI

The GREEN cats suit the supercharged engine, and the OEM outlets join your factory-style rear exhaust. This kit supplies the headers and front connections together. Choose the H.O. GREEN or full 3"-outlet package if that is the catalyst or rear connection your build needs.

Tuning for your exhaust upgrade

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

Matching products

For a 2015-2020 Challenger Hellcat, add the Kooks Hellcat cat-back if you want to replace the rear system as well. Its 2-3/4" inlet matches this OEM-outlet front package.
