question

does an eclipse have headers?

Typically the guys who buy headers on DSM are the ones who run non-turbos. However, they do make tubular manifolds/headers for the 4G63 turbo engine (they run $300-$400). Headers are a good investment on any N/A engine, but for the turbos if a bigger manifold is needed, its better to just port or upgrade (EvoIII exhman)

Hope that helps
