GMC Sierra 2500 Headers

Tubular exhaust manifolds fall under GMC Sierra 2500 Headers that reduce backpressure in your Sierra. Long-tube designs provide maximum gains while shorty versions fit tight engine bays during installations.

Header materials include mild steel being affordable or stainless resisting corrosion permanently during harsh conditions. Tube diameter affects flow velocity with larger sizes reducing backpressure but potentially hurting low-end torque.

Headers unlock exhaust flow potential and add power. They connect to GMC Sierra 2500 Exhaust downstream. Full systems at GMC Sierra 2500 Exhaust Systems. Year-specific at 2015-2019 GMC Sierra 2500 Headers.
