If you are riding on public land, the answer is YES! Most forests now have a noise restriction of around 96 db. Without the muffler there is no way you will meet this noise requirement. Also, when removing the muffler, you will probably be removing the spark arrestor which is almost always required on public land - - without this simple screen in the tail pipe, the motor can shoot sparks out the pipe, igniting wildfires.
Some stock pipes have a removeable baffle , others dont . If yours can be removed there should be some bolts or screws at the back of muffler . Remove the screw and the baffle should pull out with a little tugging .
A clogged muffler can.

Are you trying to remove the exhaust manifold,the muffler,or just the line running from the manifold connection to the muffler?
A bad muffler on a 96 civic could cause loud exhaust noise. The muffler could cause hard starting if it is stopped up.
It is held on by a small metal clip. Remove the clip and pull the injector out.
yes. you just cut it out and connect the muffler with a pipe available at most auto supply houses. use clamps if you can not weld. the car gets slightly louder but not as bad as with a holed resonator ........ or you can get it replaced at most muffler places for about 200.
No it is not a bad thing. The muffler was invented to muffle the sound. The muffler does not enhance anything. However, the muffler stops the engine being noisy and it is a LEGAL requirement to have one, if you take it off, the police will stop and fine you and your car may be crushed.

It is not bad to run it without a muffler with a straight pipe. But remember the louder it is doesn't necessarily mean the better the performance.
Your bad muffler might be part of the reason your check engine light comes on. Usually, your bad muffler causes something else to go wrong and that causes your check engine light to come on. Problems cascade.
