Aftermarket Exahust, do I have one?

Okay just put my car in to TWOTECHS today ( Brill as usual wouldn't go anywhere else ).

Turns out the annoying elusive rattle was a dodgey exhaust clip under the middle of the car, (if you remember from another thread).

Mechanic thinks I might have a aftermarket exhaust, how would I find out? I haven't heard/drove another 200 close up so can't compare the sound.

Anyway, who ever done something to it bodged it all up and the pipes were knocking against eachother, hence the annying rattle, just replaced a U clip :smile:.
 
take a pic of it and we will be able to tell...anyway if your back box looks like this than its a standard one:
