Give your Hellcat a stepped stainless header upgrade
Pair your supercharged Hellcat V8 with Kooks long tube headers that step from 1-7/8" to 2" before the 3" collector. The package includes MLS header gaskets, bolt kits and the specified O2 extension kit; matching Kooks front connections are purchased separately.
SKU: 31032500
Choose the connection pipes with the headers
These headers require Kooks connection pipes to complete the front exhaust. Choose the catalyst arrangement and rear outlet around your Charger or Challenger installation, so the headers, front pipes and retained rear system match.
Useful fitting parts are supplied
The CAS-104322 O2 kit includes two 6" and two 18" extensions. BK111 stainless HEMI header bolts, BK114 ball-and-socket bolts and a pair of SS-755872 MLS header gaskets are also included. Those are supplied parts, rather than extras you need to add again.
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.
