Thanks for the comments re the exhaust pipes
It's on the list things to get looked at
Other things that we are thinking about doing to it include putting in a new head unit (LED touch screen), VWR air filter, and VWR stage 1 re-map
It's also a DSG (which neither of us has driven before) and we're having a bit of fun getting used to it... might have to call the car 'Christine' as it appears to have a mind of it's own!!
