Keep the larger OEM rear connection on your 6.2
Finish your 6.2-litre GM truck's Kooks header conversion with the right rear outlet. This Performance-catted Y-pipe takes 3" front pipework to the 3-1/2" OEM rear interface for the 2009-2010 truck applications.
SKU: 28563200
The 6.2-specific rear size
The 3-1/2" rear outlet is an important difference from the 2-3/4" arrangement on the smaller-engine Y-pipe. Match the connection to your own exhaust as well as choosing the correct engine.
Catted front assembly with clamps
The 16-gauge 304 stainless Y-pipe includes 300-cell Performance cats and fitting clamps. Ball-and-socket front joints require matching Kooks headers; the rear joint reuses OEM hardware. These cats are for naturally aspirated use.

Frequently asked questions
Is the outlet the same as the 5.3 version?
This 6.2 SKU uses a 3-1/2" OEM outlet. The smaller-engine version uses a different rear connection.
Can I use these cats with forced induction?
They are for naturally aspirated engines; choose a suitable catalyst for a boosted build.
