Mandrel-bent tubing moves the exhaust easily and quickly away from the head, this transition reduces HP loss because of the normal back pressure in an OE manifold.
However, for peak performance, a set of headers should be combined with a full-length performance exhaust system. Hooker and Flowmaster do exhaust right. There are 4 main types of Headers you will find, here are the features of each. Cast iron manifolds are available for certain select vehicles. While cast iron is heavier than other materials, it soaks up heat better, a plus for emissions, and it prevents unwanted heat from radiating onto other nearby components.
Performance cast manifolds differ from OE by offering smooth flow and better design. Being cast iron means they will provide years of leak-free performance with less under hood noise than traditional headers. Cast headers are heavier than a tubular version but with very little care will virtually last forever. They are heavily supporting LS engine applications.
Cast would be the choice of those who want increased performance with virtually no maintenance and no annoying header leaks. However, applications are very limited. Most hot rods run these since they are close to the engine and usually clear narrow frame rails.
The shorty design offers performance gains slightly above the factory exhaust manifold but does not provide maximum HP in the lower ranges. This design offers longer primary tube lengths, they usually combine into a four-way collector with a flange to bolt up to the rest of the exhaust.
The extra tube lengths step up the low and mid-range performance numbers and still offer a solution for those concerned with ground clearance.
This would be the most commonly known style, once upon a time, these were all that were offered. Here at Speedway Motors we list these dimensions on each product page, and you can narrow your search results by them as well.
Header wrap or exhaust wrap is a very effective way to reduce under-hood temperatures. It works by insulating the header tubes retaining the heat inside the headers and greatly reduces the heat radiating from the headers. It can be used in nearly any application and is available in black, white, and titanium colors titanium is shown below. It is easily secured to the header tubes using header wrap ties or stainless steel hose clamps.
