About this part
ATAK Cat-Back, fitment-checked
ATAK for the ZR2 and AT4 trucks, completing the three-series set. Turn-down tail pipes and a valve simulator are common to all three.
The off-road GM trucks get one system in each of Borla's three series, and this is ATAK. All three share the vehicle conditions — Chevrolet Silverado 1500 ZR2 and GMC Sierra 1500 AT4, 2024 to 2025, 5' 9" short bed — and the same construction features: tail pipes that turn down rather than exiting straight, and a valve simulator built into the system so the factory electronics are accounted for.
