If they know what they are looking for, and the plate is thicker than a steel gasket would be, then yeah I reckon they can. They wouldn't need to prove it there and then, they would just simply report it down with anything else they find. Same goes with a suspension lift. A mate of mine got done by a Mansfield copper in Alexandra and they just noted down the lift is too high. Not by how much.
Yeah mate , they can check. Here the cops set up nets where they railroad cars through a car park. Usually a large library car park or a garden car park. They have everything there. Bretho tests, drug tests, Sheriff, highway patrol, EPA etc... They pull out a fact sheet on their computer for your vehicle and go over it with a fine comb. They sit there all day, and the next day there is at least 30-40 cars cannaried or clamped down for various things.
I went through about a year and a half ago... And they were too busy shafting me for the decibels for my straight through exhaust to look any further.
My mate recently went through with his Forester diesel which has the DPF filter burn off thing on it... And they spent a bit of time making sure he didn't delete it, as like the EGR, people commonly get rid of it as it's just shit.
Usual cops and highway patrol would be none the wiser, but when EPA is there they know what's going on.
