1-3/4" W2 Step Headers

1-5/8" O.D. primary tubes steps up to 1-3/4" secondary tubes with 3" 3-bolt collectors

� Cylinder head center bolt-hole pattern spread must measure 3-15/16" to use this header

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

� Recommended for 320-575 horsepower

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

� Full length header design for proven power gain

� 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.

� 3/8" thick laser-cut header flanges contoured for a leak free fit

� 3/8" thick laser-cut 3-bolt collector flanges

� Removal of the torsion bars not required

� Easy spark-plug access

� Coupled with a TTi Exhaust Systems these headers become even more efficient!
