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 is ARH's dedicated K2XX-era 6.2L header (2014-2018 only), separate from their 2019+ T1XX part, with a catted Y-pipe. GMC Sierra fitment is not confirmed on this specific listing, so treat it as Chevrolet-Silverado-verified only for now.
