This could be a number of things based on the limited information given. One thought is that it might be the cat in the exhaust box breaking up and blocking exhaust fumes going out of the exhaust system tailpipe.
Way to check might be to see what pressure these is at the back exhaust box OR take car to an exhaust specialist.
