why does my 325 touring sound so diferent to a sport on idle

[gorgeee]

hi all
i have a 91 touring and it sounds so different to me mates sport even when cranking it over let alone on idle and when giving it a rev
the only thing thats different is my tourings a high miler and the sport isnt
but the 2 cars engine wise are identical and i thought the exhaust is the same too.
even when turning the sport over it has a much deeper and sweeter sound to my touring?
any ideas or has any1 else noticed this?
could the sport have a different exhaust?

anyone?

Probably down to the exhaust, different makes, different sounds!
They really can differ a lot!
