What could I use to put on the exhaust pipe while my car is in the garage to get the fumes outdoors? I want to start the engine, but the rear end is up on stands waiting for brakes. Even with the garage doors open it gets pretty stinky fast. If I could run a hose ouside I could keep my brain cells intact (and the cold air outside). I've seen garages with silver hoses that go through the door. Has anyone done this at home? What did you use?
BTW I would still crack a door and my garage is by no means airtight. I won't be doing it long term, just for the occasional 10-15 minute warm up to keep the engine oiled and the battery charged.

 

Dryer duct from most any home hardware store will work. Its an aluminum hose thats bendable, expandable, etc. I've seen a few backyard garages use it.

 

I'd prefer flexible exhaust tubing. Some Napa stores will have it, and an exhaust shop is almost certain to carry some. It's thicker and more durable than dryer ducting.

 

You might also want to get a fan and run it facing outside to suck some of the bad air out.
