Thanks for advice. Does the N52 benefit from tuning at all? I'm checking out the intake manifolds and headers. If you upgrade a header would it be wise to make upgrades to the rest of your exhaust system as well or can you get away with just doing a header and then the manifold. Or vice versa, do the intake manifold and then the header?

Which upgrade would would produce results independent of the other? It's my knowledge that the exhaust performance relies on your HP.
