Best bang for the buck, and likely sound, would be to stay stock as far as rear cans, and just replace the midpipe with MadDad or the like. So far it has been speculated that it is just the end quad that is different on the 1///M, all else same as the 135i, so the aftermarket midpipe for $500 or thereabouts would give you some nice sound, modest gains, and weight reduction.
