Give your 5.3-litre truck a proper front exhaust upgrade
Upgrade your 5.3-litre GM V8 with 1-7/8-inch Kooks long tube headers and a matching Performance-catted Y-pipe. Its 2-3/4-inch OEM outlet lets you keep a compatible rear exhaust.
SKU: 2862H420
The rear connection is matched to the 5.3
The kit uses 3" collectors and a 3" Y-pipe before reducing to the 2-3/4" OEM rear interface. That outlet is different from the equivalent 6.2 kit, so the 5.3 engine specification matters when choosing the complete package.
Choose the cats for your engine
Performance cats suit a naturally aspirated 5.3-litre engine. For a supercharged or turbocharged truck, choose a catalyst package designed for forced induction. You can match your model, trim and year in the vehicle table.
Tuning for your exhaust upgrade
We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Contact us to discuss the right tuning route for your vehicle.
