Tests have indicated that the late model vehicles with lower operating RPM ranges function (scavenge) more efficiently with the "TRI-Y DESIGN". "Tri-Y" headers were specifically designed for these engines.
While 4-tube headers are well suited for some applications, the "Tri-Y Design" is significantly more effective on most street and off-road applications including the late-model, low-compression "Big
Blocks". Clear Image TRI-Y headers bolt directly onto the heads with no modification to emissions or alternator brackets. A box end wrench can be used on every header bolt. The block does NOT have to be lifted for installation. Removal of the starter is NOT required. These headers fit better than the factory manifolds and have no clearance problems or heat related problems. You will NOT have to use heat shielding of any kind.
CERMACHROME is a ceramic coating which mimics a chrome finish. It is rated to 1300° Fahrenheit and reduces radiated heat under the hood tremendously, as well as improving scavenging, (rate and method of exhaust gas flow through the header tubes). CERMACHROME contains aluminum flake which is polished to allow the polished metallic finish. Satin ceramic is also available and is rated to 2000° Fahrenheit, due to the absence of metal.
