yes it can damage the engine by burning up the valves

It doesn't burn the valves it warps the valves. If the straight pipe is short enough it will cool quickly and that will cool the exhaust valve to fast which might cause the metal to warp. Some will say the engine needs to have back pressure to run, to them I say to watch a drag race at a track where there are rail cars running and tell me where the back pressure is in there exhaust. You will see them plugging the exhaust pipe after they shut the engine down though.

Back in carburetor days, when people put on a straight pipe, it could confuse the carburetor into running lean, warping the valves and burning down the motor.Fuel injection won't do that. Not having a catalytic converter should confuse your computer, though, causing the computer to go rich, into "limp home " mode. If you don't have a "check engine" light, though, it must be working all right.

Ford started with the dual plug design in Mustangs and Rangers with the 2.3 in 1991 for improved emissions, power increased from 88HP to 105, and that same year they did away with the distributor. They have run on coil packs ever since. Simply put, removing the spark plugs will severly hurt driveability. The EEC disables the pulse to the injectors and your engine's timing will bounce all over the place. Blow it up? No. The EEC prevents that. Mechanical failure will be due to a failing or failed internal part. Straight piping a four cylinder for any reason is just plain idiotic.

I agree with Brent and Pave Hawk. It won't ruin your engine. But a straight pipe, without the correct back pressure, will just run lean. Rednecks will tell you that it increases power, but really it just enriches the fuel-air mixture. You want more air in the cylinders. It makes it more efficient. Racers straight pipe to run more gas, like a burst of power, not something meant for gas efficiency. That's why the loudest trucks on the street chug so loud to get up to 30mph. Straight pipes are for high rpms power. There's never a need to straight pipe a 4 cylinder. If you want to get a good sound, go to headers. My 1993 ranger 2.3 dual plugged makes a beautiful hog sound with the headers and stock exhaust. A tip or resonator can louden the sound. Straight pipes just make it vibrate.
