A cat-back exhaust system replaces everything from the catalytic converter back - resonator, muffler, and tailpipes - while leaving the factory manifolds and catalytic converters in place. It is a bolt-on install that mainly changes exhaust sound with a modest, real airflow gain.
why this one — This is Borla's dedicated 6.2L-specific S-Type system (not a shared 5.3L/6.2L part), confirmed on Borla's own site for both 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500. Note it is only listed for Extended Cab/Standard Bed and Crew Cab/Short Bed configurations - other cab/bed combos are not confirmed on this SKU.
Borla's own product page says the system "unleashes hidden horsepower" via less-restrictive flow but does not publish a specific hp/tq number for this SKU.
