2-1/8" Raised-Deck "Step" Headers



Recommended for 600+ horsepower

Our 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.

  • 2" O.D. primary tubes / steps up to 2-1/8" secondary tubes / merged into 3.5" collectors

  • 3/8" thick laser-cut header and collector flanges, contoured for a leak free fit

  • "Step" design provides low-end response and top-end horsepower gain

  • Above the steering center link design (under chassis) offers maximum header to ground clearance

  • Full length header design for proven power gains

  • One piece header tubes / No slip tubes

  • Header Sets Include:  1/16" Header & Collector Gaskets, Header Bolts (12pcs) and Reducers/Adapters for hook-up to your Exhaust System.
