Engine rattle and only half of exhaust working

So this morning I noticed my engine making a noise like a rock was inside of it and when doing a walk around of my car I noticed only the right two exhaust tips were actually putting out exhaust. The left two weren't doing anything. Before I go to a shop and pay a rediculous amount does anyone have any idea what it could be? It is a 2001 M3 that otherwise is in great shape.

So, on my way to work my battery light cane on, so I think the rattling may have been the alternator.

However, the radiator light also came on and as I was parking the temp sky rocketed and my power steering went out (I am guessing due to the temp). So now I am waiting for the store to own to buy some coolant and hope that is all that is wrong. But I am at the notorious coolant system failure mileage so it could very possibly be more than just low coolant.

That doesn't sound good. I'd get it towed.

Any way to figure out which other than trial and error?

Update: found the problem, my idler pulley was stripped, no plastic, no bearings, just the metal at the core. I replaced that and it fixed everything. Except for the crack in the coolant reservoir that is. Plan to pull that out today and see if I can fix it. If not, anyone know the going price for one? I am guessing it is an OEM item only.

Go to RealOem to find the part number, then ECStuning for a price. Then go to your local BMW dealer and when they tell you it's a jillion dollars, tell them how much ECStuning has it, and they will probably match it. They will either have it in stock or have it the next day. It will be OEM or an OEM replacement and you won't pay shipping.

Do the entire cooling system. Don't bother just going piecemeal since you'll have to do it all soon anyways.

if you're not going to have the work performed at a dealership, get the M3 cooling kit from "GetBMWParts.Com". It has everything you need for the complete replacement of the cooling system.
