1994 Toyota 4Runner with bad muffler/tailpipe – what to do?

My 1994 Toyota 4Runner (V6, RWD) has a bad muffler and/or tailpipe. It runs loud, but not undriveably loud. Today I took a good look under there for the first time since buying the truck (pictures within) and I would like some advice on the best and most cost-effective way to proceed. Bonus mystery switch question at end. [more inside]

Metallic rattling noise coming from exhaust pipe

Recently my car (2008 Vauxhall Zafira) has started making a metallic rattling sound when (a) the engine is turning over at very low revs (i.e. when starting the engine) and (b) when going over bumps. When the engine is idling, or when driving along on a smooth road, the noise disappears. I can recreate the noise by grabbing hold of the exhaust pipe at the back of the car and wiggling it from side to side, so I assume that the noise is due to some bit of metal coming loose and banging around. I'm quite keen to fix this myself; can anybody suggest a more specific first troubleshooting step than "crawl underneath the car when it's cool and try to find the loose part"? I have no way of raising the car up, but I reckon if I park it with one side on the curb I can get underneath and take a look. If successful, I will update this thread with my findings :-)

Don't Leave Me Hot and Hanging

How do I wire my new bathroom exhaust fan? The old fan has three functions (fan, light, nightlight) and therefore connects to a triple switch on the wall. It also means that there are two runs of wire to it. The new fan has only two functions (fan, light) and therefore only needs one run of wire. How do I wire this thing up; what do I do with the extra run of wire? [more inside]

Please help us avoid mold in the attic.

We just bought a house, and the bathroom fan currently vents into the attic. I know this isn't good, and I have done a bunch of googling, but I still have questions. Like: who should do the work -- a roofer, a handyman, someone else? Is it better to vent through the roof or through the wall, as our handyman suggests? Any other things I should know?

Et tu, Maytag?

I thought I was doing an environmentally smart thing by switching our dryer vent to an indoor water filtered vent in the winter, but a friend claims the fumes may be harmful. Crap or not crap? [more inside]

would hydrogen cars cause cloudy skies?

Weird theoretical question filter: At the moment, gas exhaust from cars rises, and produces a layer of smog above large cities. If everyone used hydrogen fuel cells, this exhaust would be water vapor. Does this mean that it would often be rainy or cloudy due to this water exhaust? If not, what would happen?

Loud exhausts and motorcycles

Why are motorcycles with EXTREMELY loud exhausts allowed to be built and used in this country (US)? I'm talking about those Harley types that can be heard for a mile, and are so loud that they literally hurt your ears. I can be in my house with the windows closed and when one goes by, I can't hear anything but the noise of the exhaust. And forget about driving and having one next to you -- it's simply deafening.

Aren't there any noise laws to prevent this??

What are the primary gases produced by propane combustion?

What are the primary gases produced by propane combustion? I was just told a story about a nearby warehouse, very high ceilings, 2600 sq ft, which is being heated by umbrella-style outdoor propane heaters (think of outdoor restaurants in LA, for you left coasters). Visions of dead people litter my mind, consequently. Am I right, or confused with regard to the exhaust? Please provide authoritative links so I can pass this along without being confrontational.
