I guess header and exhaust system should do it. By the way, how does 290hp feel compared to before?

Go to mbjunkies and look up Cales build thread. He has larger tb and single runner intake manifold, headers, retune, exhaust and is pushing pass 300 I believe. All the tb and manifold is from other model mb s500 I believe
