First you remove the tailpipe (mine just unbolted, but I guess some have to be cut off). On my kit, the mounting point on the passenger side of the van there were 2 bolts pointing toward the driver's side that held the rubber piece the exhaust goes on. These bolts looked like they'd ge in the way of the bracket, so I flipped them. Now they are pointing toward the passenger side.

Then Kyle told me that some late model V'gons had a heat shield attached to the muffler. This needs to be removed (luckily my van didn't have this). Then drill the holes in the exhaust brackets as per the directions, but don't install them on the van yet. Next (it's much easier with a helper) you attach the cat/muffler to the TiiCo exhaust pipe with the OXS pointed up toward the air filter. After you have the cat/muffler bolted to the exhaust pipe, check the clearance between the muffler and the belts/bodywork. I had to bend a portion of the bodywork near the passenger side tow loop away from the muffler so it would clear. Then you attach the passenger side exhaust bracket to the muffler and get it to slip over the ends of the bolts on the mount.

the funny thing is that hole you drill in the driver's side bracket. The directions never say what it is for. It's for the strap that goes over the cat. Instead of hooking the strap in the original hooks, the post goes in that hole. You have to grind away a section 1-2" of the wider part of the strap so that it matches the width of the narrow part at the end that goes between the stock hooks. Once the passenger side is up and not interfering with the bodywork or the belts, then you install the driver's side bracket. I had to push the cat up about 1/2 an inch to get the mounting holes to line up. I installed the strap on the driver's side bracket before I installed it. I found that it would be darn near impossible to get the strap on after the bracket was installed.

That's about it. Once you're sure the exhaust won't hit anything, tighten all the bolts up and have a can of the beverage of your choice. :)

 Again, many thanks to Kyle Wade for his help!
