Performance Headers - Chevy Silverado/GMC Sierra Big Block V8 (1986-1995)

Unleash your big block's legendary power with performance headers engineered for 366/396/402/427/454 V8 engines. Eliminate restrictive factory manifolds and unlock massive horsepower gains by letting each cylinder breathe freely.

Why Headers Make a Difference

Headers provide each cylinder with its own exhaust pipe, eliminating cylinder interference and backpressure that robs power in factory manifolds. Combined with a cold air intake and cat-back exhaust, headers remove all restrictions—allowing your big block to perform at its full, tire-shredding potential.

Key Performance Benefits

  • Massive Power Gains: Eliminate exhaust backpressure for substantial horsepower and torque increases throughout the powerband
  • Individual Cylinder Flow: Each cylinder gets its own exhaust path—no more fighting for exit flow
  • Enhanced Throttle Response: Unrestricted exhaust flow delivers instant power when you stomp the throttle
  • Aggressive Big Block Sound: Deep, commanding V8 roar that announces your truck's presence
  • Maximum Towing Power: Improved breathing means more pulling capability for heavy loads
  • Complete System Foundation: Perfect foundation for full performance exhaust upgrades
