I'm about to have a custom set of headers made for my M52/E30. What is the ideal size primary and secondary pipe size to use, Std M52, with M50 2.5 inlet, may get a cam swap down the track.
Does anyone know what size the factory M headers use?
I was thinking 1 1/2" primary with 2" secondaries, into a single 2 1/2" system.
Any advice on what the hot set up is would be appreciated.
