    Two reasons. First, it's what it had when we bought it 21 years ago..

    Second, the car is slightly less visible on the road than a motorbike - the top of the windscreen is about 3 inches lower than the window line on a Polo-sized car. Hence making sure it's loud (but compliant) is one way of making sure that buses don't drive over the top. It also has big horns for the same reason.

    The exhaust... It would nearly have to be bigger than the car itself

    I notice on start up every morning a really loud and rough idle... Does anyone else have this experience?
    Love that noise. It is due to the idle being slightly higher on startup. You will notice the idle drops lower after a minute or so... and with it goes the lovely sound.

No Longer a VW Owner -Loving my new 2011 Range Rover Sport - bought as VW unable to provide info on the new Toureg despite it being released overseas 12 mths ago. 2008 R36 Wagon, 2006 GTI and 2004 R32 - Gone. Sorry VW, you make great cars but until you improve your customers' experiences you will lose customers

    It may actually run a bit better with a smaller bore exhaust tho...
