Is the 3 stage intake manifold from the 330i a drop-in component or do other modifications have to be made to accomodate? Any ideas on the effect it has on noise? I would think as you increase the throttle it would give a deeper throatier sound which I really am not interested in.
And as for the software, who supplies this?
