Choose the front connections for your HEMI header upgrade
Connect matching Kooks headers to the 3" OEM rear exhaust with GREEN or H.O. GREEN catted pipes. These options cover different years of the listed Grand Cherokee SRT, Trackhawk and Durango SRT applications, so use the SKU-specific fitment rows when choosing your set.
SKUs: 34103301, 34103401
Two catalyst choices with different year coverage
34103301 is the GREEN option. 34103401 is the H.O. GREEN option and has broader listed year coverage for several applications. Both use a 3" inlet and a 3" OEM rear outlet, but their fitment should be chosen by part number rather than the combined page title.
Complete the front of your Kooks system
These stainless pipes require Kooks headers, purchased separately. They let you retain a compatible rear exhaust using the factory interface while choosing the catted front arrangement for your specific engine and year.

Is this the Durango Hellcat 6.2 connection listing?
The Durango application here is the listed SRT 6.4. Choose a Hellcat-specific connection set for a 6.2-litre Durango.
Are headers supplied?
This listing supplies the selected catted connections. The matching Kooks headers are separate.
