Headers do the same job as the exhaust manifold, but headers usually have better exhaust gas flow. Depending on the header length, it can give more power by taking advantage of a scavenging effect during valve overlap.
Our cars come with a exhaust manifold from the factory

If there is a precat or two on the Cali spec, how many of the cats will this remove(all I hope) now what about us Fed spec guys will we be left in the dust like with the 3g Eclipse, if it is set up anything like the 2000-2002 Eclipse it will just esentially make the Cali spec cars into a Fed spec.
