What would happen if you drive without mufflers? What effects would it have on the engine?

Very annoyed people.
Are you including cat. conv.?
What bonneville said. Also your local noise pollution laws may not allow it. depending on where the pipe is cut, you could get back pressure.
Depends on pipe length. If the pipes are short you will need to prevent too rapid valve cooldown on shutdown.
Er ... To short a pipe causes pop - pop when decelerating.
Yes, from lack of backpressure. Very high flow mufflers do the same. GW (whose GTO goes snap-crackle-pop, with it's Dynomax set-up)

The biggest problem would be burnt exhaust valves all engines have a certain amount of backpressure engineered into their run characteristics.

I was just curious. I installed a set of dynomax performance mufflers with tips and it sounds about the same as if the car had no mufflers at all. The dynomax setup is just a temp until I have the money for the SLP Loudmouth system
