Opel Astra strange noise at low revs

    I have a 2002 Opel Astra 1.4. Recently I noticed a strange noise when i put my foot down at low revs, which I can only describe like a blowing exhaust but it does only do it at low revs and not all the time.
    To try and give an example, if I am going up a slight hill at 30mph in 3rd and then my speed slows a little and the revs drop and i then put my foot to the floor to pick it up again, a loud noise (like a blowing exhaust) is made until I reach enough speed and about 2500 revs when the noise disappears again. With my foot to the floor above approx 2500 revs it sounds okay.

    Any ideas please?

    Thanks

    Either change down to second to stop the engine labouring, or you do have a hole in the exhaust .
    The C.V joints might be worth a look all though that sounds more like mixing a bucket of coal than an exhaust blowing.

    Thanks for the tip. I don't know much about car maintainance, so I wasn't sure if could have been the exhaust justvat certain revs.
    I should be able to get the car over an inspection pit at the weekend for a look.
