I dont think it would damage the engine, but it could damage the cat and you would probably get into some serious **** if the cops caught you.

Wont damage anyhting except peoples ears. You lost power as there is no back pressure due to no restricitons in the air flow in the exhaust.

Youll only get intoruble cos of the noise. It's not a chemical violation its a noise issue. Do you have a pipe that runs right through? or is it just cut after the cat??? if so... please dont drive! bad!

Youll get defected if they catch you. The power loss is due to N/A cars requireing back pressure, yours has zero... haha.... it wont hurt the engine but i dont reccomend keeping it that way for long!

aZk.
