Give your Escalade V a matched front exhaust upgrade
Your supercharged Escalade V has plenty of character to enjoy. These Kooks front connections let you complete a long tube header upgrade while retaining the factory rear exhaust interface. Choose GREEN, H.O. GREEN or Competition Only connections around the engine and your intended use.
SKUs: 28643100, 28643300, 28643400
Choose the catalyst arrangement
28643300 uses 400-cell GREEN cats and 28643400 uses 300-cell H.O. GREEN cats. Both catted choices suit forced induction. 28643100 is the uncatted Competition Only arrangement and includes installation hardware.
Keep the rear exhaust you already have
The 3" stainless pipework joins Kooks headers through two-bolt ball-and-socket joints and connects to the OEM rear exhaust. The installation reuses the OEM rear barrel clamps.
