Long tube headers replace the factory exhaust manifolds with true tuned header tubes plus a catted connection pipe - the biggest single airflow upgrade available for this engine, but a harder install than a cat-back or intake.
why this one — This exact SKU (CT14HCAT) is confirmed by the retailer for both 5.3L and 6.2L on the 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 - one real part covers both engines rather than needing separate 5.3L/6.2L versions.
