Blimey , as I remember it when I first joined this forum back in early 2015 there was a dedicated thread just on this topic with all the info you'd need to ' cut n shut ' the stock exhaust 👍

I’ve seen the video you referred to, and I thought it was really overcomplicating a simple job.
The cat is attached to the headers and empties into the middle chamber, a separate pipe connects the middle chamber to the rear chamber. 
A longer pipe connects the rear chamber to the front chamber. 
The exit pipe goes through the rear and middle chamber all the way to the front. 
the hole I cut is in the plate between the rear and middle chambers directly behind the cat. 
The S bend I cut out as close as possible to the plate and muffler exit point. 
it’s not that loud, specially at idle or up to 4000rpm, but has a nice sound that makes its presence known. After that it screams beautifully. 
I tour a lot so didn’t want an obnoxious drone.  
 

 FFT!

 I'll read it later 2 hung over
