3 inch exhaust for D40
Having suffered some exhaust damage it seems like a good excuse to fit a 3 inch King Brown system from turbo back.
Has anyone on here fitted a 3 inch system to a D40 (140KW) and was there any noticeable improvement?
Is it necessary to have the diesel injector pump re calibrated or whatever?
It is better to say nothing and be thought a fool, than to open one's mouth (or hit the send key) and remove all doubt.
