How do I go about installing an exhaust like this?

You will only have to rejet if you mess with the air intake, and messing with the air intake is not worth the trouble IMHO. Check out all the threads that say "trouble with rejetting" or similar. There is a new thread every week. The baffle will only make the exhaust gases escape slightly quicker. And those "trumpet" baffles like the one you are looking at will in-fact, probably slow the gasses down.
The more i look at the pipe in the video the more i think it is going to hit the ground when you tip it into a tight or fast corner. I would put it on like how Lucas has fitted his. You have to remember that when you are in a fast corner the suspension compresses so the bike is lower to the ground and that baffle is gonna hit the ground and when it does, you will soon follow. Just sayin.
If you are in the melbourne area , Megacycles make a fantastic stainless baffle that i highly recommend. I got mine for $400 fitted.
Good luck John

And one more thing. Forget about "back pressure" on a four stroke engine, its a myth.  It's only important on two stroke engines. You don't see race mechanics stuffing the exhausts of race cars or bikes, full of stuff saying" We need more back pressure". Most of them are straight out exhausts.
Yeah well just more of my  opinions, but something to think about none the less.
Perhaps some of the "back pressure gurus" can explain exactly what it is and what the benifits and or draw backs of having it or not on a four stroke engine actually are?

UPDATE

I gave some advice to wedge the baffle into the exhaust and this turned out to be a bad idea.  On my motorcycle the baffle came loose and punched a hole in the metal screens of the muffler.

If it was a straight through exhaust it would have fired that baffle a good long distance.  It really hit with some force and ripped up the metal screens inside muffler pretty good...

Use a more permanent method of securing your baffles.  Don't be dumb like me.

Also an aussie.

I'm running a pipe similar to that with k&n filter, only had to shim the needle.

My local dyno tuned one with a similar straight pipe and gave me the advice for it, this is all they did.

Bikes been running perfect for the past 6 months.
