    Speed Engineering 1-7/8" Longtube Headers & Y-Pipe Full Kit for 2014–2018 Chevrolet Silverado and GMC Sierra 1500 5.3L 6.2L applications.
    This complete bolt-on system replaces the restrictive factory exhaust manifolds and mid-pipes with free-flowing stainless longtubes and a 3" off-road Y-pipe that connects directly to the existing cat-back location. Designed for significant horsepower gains, aggressive exhaust tone, and long-lasting durability.

    ⚠️ Note: Rear (downstream) O₂ sensors are not used. A check-engine light for catalyst efficiency will appear and must be disabled via PCM tuning.
