venting exhaust

I would like to create a tube in my garage that vents the exhaust gas. It is easier to work on the 911 when backed into the garage. Any suggestions for material?

First material should be a CO detector with a good loud alarm. Be careful. It's a deeeeeep sleeeeep.

Go look for a vendor for industrial supplies. They sell tubes for these applications (oily gases, exhaust fumes). Should be Silicon based to directly fit to the exhaust without burning away.
