Exhaust headers offer better performance compared to traditional manifolds. Made from lighter steel, headers are longer and designed to reduce back pressure, unlike manifolds which are made of thick iron and can limit exhaust flow. By providing each cylinder with its own tube, headers allow exhaust gases to exit more efficiently, improving engine performance and horsepower. Upgrading to an exhaust header, is an easy, direct bolt-on upgrade for your 1994-2004 Chevy S10 or GMC Sonoma 2.2L I4. It improves exhaust flow, enhances engine efficiency, and provides a more aggressive sound.
