Keep the correct rear outlet when you upgrade your 6.2 headers
Complete your Kooks long tube header installation with a matching stainless Y-pipe for the listed GM 6.2-litre truck and SUV applications. These pipes use 3" front connections and 3-1/2" OEM rear outlets, with Competition Only, Performance or GREEN choices.
SKUs: 28613100, 28613200, 28613300
Match the engine and vehicle years
The truck application is 2014-2018; the supported SUV application is 2015-2020. The 6.2-litre rear outlet is 3-1/2", while the corresponding 5.3-litre Y-pipes use 2-3/4". Keep that distinction when matching the front pipes to your retained rear system.
Choose the catalyst for your build
Performance cats use a 300-cell substrate and suit naturally aspirated engines. GREEN uses 400-cell cats and supports forced induction. The 16-gauge 304 stainless pipes have ball-and-socket header joints, supplied clamps and reused OEM rear hardware.
