well i don't know much about that but from what i understand if the block is at the tip it may leak around the block or blow it out or go backwards and hit the engine.Now if its close to your engine more then likely it will shoot backwards and hit your engine.Either way you will mess up the engine eventually. sorry about grammer i just woke up :)
Unblock the exhaust pipe, start it up and go.
BAD
Exhaust.
He _----- --- --- -- the _------ ----. He burned his lips on the exhaust pipe.
A car that has a bad exhaust flex pipe will not pass inspection in any state that requires it. The pipe will need to be fixed before the car is inspected or it will fail.
Engine exhaust.
who has the biddest car ever
get a potato and shove it in there exhaust pipe
carbon dioxide
If it is restricted enough, the exhaust valves could burn out. Other than restriction, I wouldn't see how. Only if the pipes are pinched shut or almost completely blocked. Theres no backpressure it will stall out constantly or not start at all. (ever paint a potato black and stick it in someones exhaust pipe?) Theoretically, you can run the car with a huge gaping hole or no exhaust at all, it will sound like junk but it will run.
That big pipe on the bottom of your car with the cat and muffler on it, ends in a tail pipe, squirts pixie dust.
One can purchase a spare exhaust pipe for a car at a website called AutoPartsWarehouse. You can also buy these same pipes at a website called JCWhitney.
