Van's changed exhaust solutions, but didn't really update the plans. They did have slightly udpated plans on their website, but only took a few photos and didn't update the previous six pages of text in the plans. It took caused me a few hours looking for the old parts and I even ordered them from Van's. I noticed the difference this morning when I finished re-inventorying the parts.
I got the left side of the exhaust system completed and started on the right side. Now that I know how it goes together, the right side shouldn't take as long.
