'01 - '05 Exhaust Manifold / Header. Not only is the 99-00 exhaust manifold the heaviest stock manifold, but its cast design greatly inhibits the flow of the exhaust gasses. The '01-'05 exhaust manifold has been proven to be the most efficient and high flowing manifold when compared to the 99-00 manifolds, so it is a great way to boost your horsepower and shed some weight. The manifold comes with a heat shield and EGR tube so that it can be easily installed on a 99-00 car, this is a direct bolt on replacement.
