I added the extension to mine as I wanted it above the roof. The normal one was just to low for me and I wanted to be sure the vented exhaust would be be pulled in via the vents.

Note...I also needed to have an piece made at the local muffler shop to go over my exhaust as the chrome on the pipe was to large. (Not sure what generator you have, but my 08 TM came with a Powertech generator.)
