You might be aware that I'm planning on straight-piping my car because it currently has a non-existant exhaust note and dammit I want to hear something when pull away from Geo Metros at stop lights. To this end I'm probably going to buy some straight sections of pipe, some thermal tape (because hose clamps or welding would be too posh for this car) and ghetto-rigging the resonator, muffler, or both into non-existence.
To see what it would be like to live with a loud car in a fashion that's easily reversible, I'm wanting to unbolt the four bolts that hold the exhaust to the downpipe, then use a coathanger to move it out of the way so it's just glorious unmuffled engine goodness, drive around town for a few minutes and see what it sounds like. Obviously the difference between this and a "finished" product is seven feet of pipe and a catalytic converter (not present during my test runs since it's downstream of where this all unbolts) but it should give me a decent measure of loudness.
My question is: will the fact that exhaust gasses aren't passing through the cat and o2 sensor (I think that's what that is) screw anything up? I'm guessing the engine will start running hella-rich and I'll probably get a check engine light, but will 30 minutes of this harm anything?

You shouldn't remove the cat cuz is bad for all of us. The likely hood of you breaking something is in direct correlation to your does dance on the car to get arround.

I'm pretty sure it won't run right without the o2 sensor hooked up

Technically it'll be hooked up... there just won't be any exhaust gasses moving by it. I'm pretty sure the side effect will be it running either lean or rich (no idea which one), but I'm not sure if this'll harm anything or not.

It'll probably run rich, since the o2 sensor will always be in a large amount of oxygen it will think the engine isn't getting enough fuel and just keep dumping fuel in.

FWIW, my Jeep is running with a cat delete and glasspack courtesy of previous owner. You'll get a CEL, it'll run very rich, and it may take longer to crank over. Honestly you should be able to tell in your driveway if you can handle the straight pipe noise.

It will run fine, the computer goes into closed loop mode and you'll get a warning light. You won't break anything but it will be annoyingly loud and sound like shit. Keep the resonator at least, at best use a flowmaster muffler or similar.

Onward ho. I'll unbolt the exhaust system and see what's what, then head to O'reilly's for some straight pipes.

You should have two o2 sensors, one for upstream ( the most important) and the downstream is for monitoring catalytic performance. So, it'll run but you'll have mad CEL.
AMGtech - now with more recalls!

Once upon a time I had a Grand Prix GTP. Did a resonator and u-bend delete, but it only grew slightly louder. So if you're looking for loud, I suggest staying with muffler delete.

No, no, no, no. Don't use thermal tape.
Been there, done that. You will hate yourself. If you decide to cut off the muffler, do it so that you have enough clean straight pipe on both sides of it to clamp a section of pipe to.
Take your newly bought pipe to a muffler shop once you cut it to length, then have them blow up both ends to measure your stock pipe's outer diameter on it's inner diameter. Then clamp the new pipe on with exhaust clamps, and thank me for saving you from having to constantly fight your muffler falling off. You'll probably still only spend $35, and you'll only have to do it once.
