Exhaust rattle ?

[matthewsimone]

hi all, i have a 2002 ph2 172 and it has recently developed a rattle on the exhaust but only usually hear it upon starting the car up where it makes quite a violant broken rattle sound lol, its not snapped and cant work out where the noise is coming from backbox maybe? are there any parts of the exhaust that have common faults as its still all standard etc cheers in advance, Matt:S

baffles in mid section or the heatshield is loose

My old mans 172 does exactly this at the min. He was told it was the cat that's knackered (I have no idea about it tbh)
