For the 34 years I worked as an auto mechanic, virtually all the shops I worked in had the standard exhaust hoses and the aluminum fixture in the garage door to stick it outside. Has been awhile since I had my shop but the last time I bought these items the fixture for the door was about $16 - has a swinging flap to keep the hole covered when not in use. An 11' section of the 4" hose was about $50 but it is totally heat proof and collapse proof - you can drive all over them, even on gravel and not hurt it and they last virtually forever. You can also get adapters to couple lengths together and a "Y" connector to use on dual exhaust or for 2 vehicles. A word of caution - whatever you use will get very hot after just a little while, especially if you idle it up for more than 10 minutes or so, chose your material wisely.
