M Tech II. It's perfectly plausible, and considering the age of your car, quite likely that it was installed from the factory, it all depends on the original spec of your car. However, I don't think an insurance company would pick up on it, or particularly care if it was added; I know mine certainly wouldn't. M Tech II bumpers are very common on facelift coupes so would probably go under the radar.
See if you can find the original spec sheet of your car.
