Hi i have a 1.8 non turbo mkiv and when going along uneven roads at slow/average speed it seems as tho the exhaust is squeaking. At first i thought it was something in the dash squeking around but pritty sure it isnt. I was wondering if there is anything i can do to stop this but also when the engine revs to 4000 - 4300 ish what sounds like the exhaust seems to make a deep rattling noise its quite hard to explain. I was wondering what this could be... its ONLY at these revs is it a loose exhaust or a hole in it or something. Any help would be appreciated. Thanks Kane
