nice...but wat will actually happen to the car? cannot start or jerking?
If its completely blocked, the engine will die off of suffocation because exhaust air is trapped inside the combustion chamber and fresh air cant enter and then until a point the car cannot start. Good enough to waste the buggers time and maybe money to call for mechanic or tow the car. Even if he's a mechanic I believe he wont be thinking of clogged exhaust unless he is very experienced.
