Unleash the hidden horsepower of your GM truck or SUV with the SPDZ1 Full Polished Stainless Steel Long Tube Headers, engineered for maximum flow and unmatched performance. Compatible with 2007–2014 Chevy Silverado, Suburban, Tahoe, GMC Sierra, and Yukon models equipped with 4.8L, 5.3L, 6.0L, or 6.2L V8 engines, these headers are built to outperform stock manifolds in every way.
