Sounds like you have a classic case of a blocked catalytic converter - I quick test is to warm up the car to when it does the problem Shut off the car and loosen the bolts the hold the engine pipe to the engine thus giving the engine a different path to release exhaust gases and take it for a ride - Yes it will be noise but will give you the answer. Depending on where you live it can be illiminated to repair your problem. Make sure the rest of the exhaust did not get 'cat' refuse into it. Good Luck
