About this part
S-Type Cat-Back, fitment-checked
A two-year span across named trims on both badges, and the adapter note is unusual: two of adapter 60706 are called for on the longer wheelbase, not one.
Most adapter notes in this range name a single part; this one asks for a quantity. Two of adapter 60706 are specified for the longer wheelbase, which is worth catching at ordering time rather than after the parts arrive. Coverage is the Chevrolet Silverado 1500 in High Country, LT Trail Boss, LTZ and RST and the GMC Sierra 1500 in AT4, Denali, Denali Ultimate and SLT, 2024 to 2025, factory split rear exit only, with the factory tips reused.
