WHEN YOU WANT TO MAKE ALL OF THE POWER

This is the Invidia Equal Length Big Piping Exhaust Manifold. This type of manifold is ideal for those of you looking to surpass large horsepower figures that would otherwise be limited by the flow capacity of the factory exhaust manifold. When shooting for 600+ horsepower and beyond, two of the main ingredients that seem to be key factors are a larger piping diameter, along with an equal-length design. This with smooth bends as much as possible within the manifold design will allow for an unobstructed flow path for the exhaust to exhale the exhaust gases as proficient as possible for those with moderate bolt-ons.
