Small Block "Step" Headers

TTI's Small Block "Step" Headers are constructed of 16 gauge mild steel tubing, mandrel bent on sophisticated computer controlled bending machines for precise fit and uninterrupted exhaust flow.  The mandrel bending process maintains a constant inside diameter of the tube for a smoother finish with no restriction of flow and no crimping of the tubes.
