What you'll need is a set of allen keys or a set of allen keys on a 3/8" drive for a rachet. This will make life so much easier. 1/4 and 3/8" drive sockets and rachets.
This is the way I did mine and since the instructions suck something fierce, I figured I would share.
The pipe install is very simple. The main key is to loose fit it all first and let it hang. tighten from there.
These little brackets(there are two of them)

werent mentioned in the instructions i have.
they slide into the back of the pipes that are welded together like this

this bracket bolts to where the original lower bracket bolted to for your factory exhaust, and also onto the back of those pipes that are welded together that you just slid those smaller double brackets into.

the two main pipes of the exhaust are pretty self explanatory on how they install. again, install them loose. Here, I went ahead and installed my o2 sensor. there are two spots for the o2. a large port and a smaller one. Our bikes use the smaller one and the pipes come with a plug for the larger hole. you can see i went ahead and installed it in the picture of the black bracket.
here is a shot of the o2 sensor

Before you slide the double pipe onto the front and rear pipe, there are two (one for each pipe) thick clamps that tighten down with an allen head. loosen them as much as you can and slide them onto the double pipe at the end where the front and rear pipes will connect. then slide the pipes that are welded together into the head pipe and the rear pipe. With everything together, tighten down the clamps a little just to hold it all in place, and you will have two little spacers to install behind your big black bracket before you start the bolts at the bottom. here are the spacers

by starting the bolts, you have everything holding in place. I started with the front pipe and worked my way back, tightening everything as I went. pretty self explanatory.
the heat shields slide on and then you have to get them at the right angle to pop onto the pipes themselves. the rear pipe, make the clamp adjustments toward the top side of the bike. an extra set of hands works wonders here(thanks again to my wife!)
The front pipe, it was easier to make all the adjustments toward the bottom. The front pipe's upper most heat shield clamp i pointed toward the front of the bike it was a breeze to get to.
I hope this may help guys. I tried to take pics of the important parts.
