What tuning options are there for the E36 323,
I been reading that you can put the 328 exhasut on which might open a few hp, but surely your going to lose torque as the 323 is a 4-2-1 system where as the 328 is a 4-1 system.
ALso you can put the M50 inlet manifold on? How can I tell the difference between the manifolds looking at them?
What kind of power gains have you guys with a 323 got and what mods have you done?
