HEADER FEATURES
• 2.0" O.D. Tubes
• 3.5" Collectors
• 3/8" thick Flanges, laser-cut, contoured for a leak free fit
• Under chassis design: Above the steering center link design offers maximum header to ground clearance
• Full length header design: Proven power gains vs. shorty header designs
• Recommended Horsepower: 500-750
• Torsion bar removal: Not required in B & E-body applications, however, removal recommended in A-body applications
• Header 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.

HEADER FITMENT
• 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. (Click here for the factory dimensions)
• 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.
