Exhaust Manifold is made to be used with waste gate style turbines. The craftsmanship and design of this particular piece is obviously top of the line and is made with high quality stainless steel. Exhaust gases will now flow more efficiently to your turbine which will help the turbocharger spool earlier. This will in turn increase acceleration as well as overall performance. Made of high quality certified T304 stainless steel and is TIG welded for a more precise and perfect finish. For ultimate spooling and response, turbo Manifold can yield much higher top-end giving you more peak horsepower as a result of equal length runners.
An intercooler is essentially a radiator for forced induction, allowing the compressed air to cool before entering the engine. Although not required, an intercooler is a highly recommended part of any forced induction setup, turbo or supercharger.
