Hooker 2451-3HKR Exhaust Header

Compatible with 1967-1974 Camaro,1965-1974 Chevy Full Size, 1964-1974 Chevelle/El Camino, 1970-1974 Monte Carlo, 1968-1974 Nova, 283-400ci Small Block Chevy, 1.625 in. Primary Tube x 3.00 in. O.D Collector Size;<br><br>Hooker Competition headers offer the best value in the high performance header market. Designed for the value-conscious buyer who is running either a stock or mildly-modified engine, Hooker Competition headers offer premium features at a very competitive price. Made of durable 16 gauge mild steel tubing, the Hooker Competition header design utilizes a long transition collector to reduce back pressure and increase exhaust flow. A perfect sealing surface is assured with the 5/16 in. machined flanges. Experience has proven that this flange size is ideal to maintain header integrity and be pliable enough to seal each exhaust port. Tubing is mandrel-bent to maintain metal strength and provide consistent tube diameter at radii to maximize performance. Hooker Competition headers have a standard finish that features a heat-cured, high-heat-resistant paint. Optionally, the famous Hooker Ceramic Thermal Barrier Coating is available.<br><br>The Darkside coating also provides improved thermal resistance as compared to traditional silver ceramic (1700° F vs. 1300° F) making it highly recommended for supercharged or NOS applications as well as for reduced under-hood temperatures.;

• Provides unique styling enhancement that is equally pleasing in either a nostalgic retro application or a modern hi-tech build. As this coating is not burnished after its application, the surface appearance is more consistent than that of a silver cerami
• Increased corrosion protection ensures long service life and maintained appearance of investment
• High-efficiency thermal properties limit heat migration through the header assembly, which in turn lowers under-hood temperatures for more performance
• Provides a higher heat tolerance threshold than available from silver ceramics (ours or any of our competitor’s) and is therefore recommended for any applications producing elevated exhaust gas temperatures, such as when using superchargers and/or
• Works with factory power steering and power brakes
