Performance Exhaust Overview:
A performance engine is an integrated affair. When you modify one set of components, you have an effect on other systems. On a mildly modified engine, a minor upgrade in either the cam specs, exhaust system, or intake can be done independently. For performance, camshafts work best when integrated with upgrades in the exhaust and intake. The exhaust system is probably the first area to improve on any engine, because this will only enhance future modifications. The study of Physics tells us that we usually can’t get “something for nothing”, but when adding headers and improved exhaust components to an engine, we almost do. The improved exhaust flow and velocity derived from tubular headers and free flowing mufflers is one of the only modifications you can make to an engine which will improve both power and fuel economy.
These outstanding headers are built especially for Motorsport to our strict specifications. The thick exhaust flange is flat machined to promote a consistent seal. It also prevents warping and eliminates the need for spacer height modifications. Exhaust ports have high-quality welds to ensure leak-free performance. We use 1 1/2″ primary tubes to ensure increased exhaust flow without any performance loss. Can be attached directly to the stock exhaust components or our Motorsport performance exhaust systems (choose stock or 2 1/2″ adapter (pipe diameter of the exhaust you are going to use)). Special installation gaskets are included (do not use original equipment type exhaust gaskets with headers). This header configuration is for original 1970-1976 cylinder head “square” exhaust ports only.
This header comes with a highly durable and effective Aerospace Thermal Barrier Ceramic or TBC coating, which is good up to 1300 degrees fahrenheit. The satin “polished” silver finish coats both the inside and outside of the header. This does a number of things. First, it cuts radiated heat by approximately 40%. Not only does this help to keep your under hood rubbers and plastics from drying out, it also lowers the temperature of the fuel and air which translates into increased performance. Secondly, locking much of the exhaust heat in the pipe keeps the exhaust flowing more rapidly, also increasing performance. Finally, it protects the header tube metal underneath the coating from corrosion. Please note that the adapter portion is not coated.
