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 — Kooks' own page confirms this exact header fits continuously from 2014 through 2026, spanning both the K2XX and T1XX chassis generations without a separate part - useful if you are not sure which chassis generation your specific truck is.

why no number is shown

Kooks does not publish an independent hp/tq figure for this header set on its own product page.
