Choose a complete Super Street upgrade for your G8
Bring Kooks Super Street headers and catted OEM connection pipes together for your G8 GT or GXP. Choose Performance or GREEN cats with 1-7/8" stainless headers, joining a rear exhaust using the factory-style interface.
SKUs: 24201420, 24201430
Headers and catted connections together
Each G8 package supplies the Super Street headers and matching catted connection pipes. The outlets join your factory-style cat-back, giving you a front exhaust upgrade while keeping the rear system you already have.
Choose the cats for your modifications
Performance cats suit naturally aspirated engines. GREEN supports forced induction. The GREEN package has 3" collectors and connections that transition to 2-1/2" OEM rear outlets. Both join a compatible factory-style cat-back.
