Long Tube Exhaust Headers for 1999-2006 Silverado Sierra 1500 V8 - KSP Performance

Upgrade your 1999–2006 Chevy or GMC Silverado, Sierra, or Avalanche 1500 with this stainless steel exhaust header. Designed for 4.8L, 5.3L, and 6.0L V8 engines, it fits both 2WD and 4WD GMT800 models. The 4-1 high-flow design and mandrel-bent tubing improve exhaust velocity and reduce backpressure for better throttle response and performance. TIG-welded CNC flanges ensure a precise, leak-free fit, while the polished finish resists corrosion and heat discoloration. A direct bolt-on installation makes this header a durable, efficient upgrade for your truck.
