The exhaust system went on easily as per the manual.
The length of the extention pipes had to be cut to where it exited the cowl at a desired lenth. So until you have completed the bottom cowl this step has to be delayed. It is easy however, to install and remove the extentions pipes because they are held on by springs tension.
You do have fabricate and install a clamp part to fasten the bottom end of the extentions to the firewall.
To cut the extentions I had to buy a chain type pipe cutter since all of my available cutters were slightly to small to work.
