Maybe the exhaust is scraping against something..as the engine moves slightly?

It doesn't sound like something rubbing. I reckon the guys who fitted the exhaust have managed to dislodge something. MRC recently gutted the precats – I wonder if they've disturbed the recently welded downpipe...
i had a exhaust mount rub a heat sheild once after a exhaust was fitted made same kinda sound check that kinda stuff heat sheilds can make nasty noises
