Description

Fix the “Chevy Tick” & Wake Up Your Vortec V8

Is your 1999-2006 Silverado or Sierra ticking on cold starts? The factory cast-iron manifolds are notorious for warping and snapping bolts, restricting the potential of your 4.8L, 5.3L, or 6.0L Vortec engine.

The Solution: Flashark Long Tube Headers with Y-Pipe. Eliminate the restrictive stock manifold, fix the exhaust leak permanently, and unleash +20-25 HP and massive torque across the entire 4.8L, 5.3L, and 6.0L lineup.
