HI I HAVE A MK4 GOLF 1800 20v AND THE EXHAUST SOUNDS TO BE BLOWING WHEN CAR IS STARTED FROM COLD,BUT WITHIN A FEW MINUTES AND THE CARS WARMED UP A BIT THE BLOWING STOPS,JUST LIKE THERE IS A CRACK IN PIPE OR THE MANIFOLD TO DOWN PIPE IS FAILING,SO I HAVE REPLACED GASKET BUT STILL GET BLOWING ON START UP.
HAS ANY ONE ELSE HAD THIS PROBLEM OR GIVE SOME ADVICE.
DOES ANYONE KNOW HOW LONG CATALYTIC CONVERTORS SHOULD LAST FOR
