Keep the 6.2-litre rear connection with your Kooks headers
This Kooks Competition Only Y-pipe uses 3" front tubing and a 3-1/2" OEM rear outlet for the GM 6.2-litre applications. It finishes the long tube header conversion while retaining the compatible factory rear system.
SKU: 28543100
Different truck and SUV ranges
The truck range is 2007-2008 and the SUV range is 2007-2010. Choose the individual vehicle row for your application, not just the 6.2-litre engine badge.
Clamps included for the front installation
The 16-gauge 304 stainless pipework uses ball-and-socket joints to Kooks headers. Fitting clamps are supplied and the OEM rear hardware is reused.
