Bring a matched Kooks upgrade to your naturally aspirated SS
Upgrade your Camaro SS with 1-7/8" Kooks long tube headers and Performance-catted front connections. This package suits the listed LS3 and L99 6.2-litre applications, joining the 2-1/2" OEM rear exhaust interface.
SKU: 2250H420
Headers and front cats supplied together
The stainless headers use 3" collectors feeding the supplied 3" front connections. The pipes transition to 2-1/2" OEM rear outlets, letting a rear system using that interface remain in the build.
Choose it for naturally aspirated use
Performance cats are specified for naturally aspirated engines. This is an SS package; the supercharged ZL1 and a boosted SS need an appropriate forced-induction catalyst arrangement.
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.
