Keep your GM rear exhaust with a competition front conversion
This Kooks Competition Only Y-pipe completes the matching long tube header installation on your 2009-2013 GM 4.8- or 5.3-litre truck or SUV. Its 3" front pipework joins the 2-3/4" OEM rear interface.

Stainless pipework with fitting clamps
The 16-gauge 304 stainless tubes use ball-and-socket header joints. Clamps are included, while the OEM rear hardware is reused.
