Bolt-hole measurement

FEATURES ...

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

Primary tube size:  1-5/8" O.D.

Secondary tube size: 1-3/4" O.D.

Collector size:  3" with 3" 3-bolt flange.

Flanges:  3/8" thick, laser-cut, contoured for a leak free fit.

Material:  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.

Step design:  Provides low-end response and top-end horsepower gain.

Under chassis design:  Above the steering center link design offers maximum header to ground clearance.

Full length header design:  Proven power gains vs. shorty design.

Recommended for:  320-575 horsepower range.

Torsion bar removal:  Not required.

Header set includes:  Header gaskets, 12 header bolts, header reducer adapters with 3-bolt gaskets & hardware.

      Coupled with a TTi Exhaust Systems these headers become even more efficient!  [Click here to see exhaust systems]

      Prices do not include Shipping, Handling or California Sales Tax, if applicable.  Prices subject to change without notice.

      Our headers were designed to fit with the engines located to the factory specifications.  If the engine is not located correctly in the chassis, the headers will not fit properly.  We strongly suggest you check your engine location prior to installation.

      Due to various manufacturing designs, aftermarket parts, engine configurations, suspension combinations, etc... TTi cannot ensure headers and exhaust systems to fit all combinations.  However, we have done our best to accommodate both factory and aftermarket component combinations.  In some cases, slight modification or repositioning may be required on your part to clear the specific situation.

     

    A-body:  No need to remove your torsion bar!  The Drivers-side #7 tube is designed to be removed to slip around the torsion bar.

    B,E,F,M-body:  No slip tube, one piece header.
