Hey man, its still on going but so far I have replaced the mid section muffler with this: https://www.redlineperformance.co.nz/product/resonator-universal-round-25-mild/
and got the 3rd cat replaced with basic y piping (cat delete).
As far as sound goes, it has made it a little deeper at idle and made everything just a fraaaction deeper overall. Volume has also increased a little as well as a touch of raspiness which was the goal. For the money (150 from pitstop) I would saaaaaay its somewhere between worth it and not worth it to be fair. If you want a sound clip I am doing car "stuff" this weekend so can add that to the list.
My next step to finish off the project is to take some spare stock mufflers, open them up, gut them out, seal them back up and chuck them on with some slightly bigger tips. This should make it considerably louder in conjunction with what I have already done and will hopefully be near what I am after.
This is my playlist of videos I have found around youtube that have a clear description of the exhaust mods and the sound it produces

My goal sound for my budget would probably be this: https://www.youtube.com/watch?v=YzeArKE3Jc8
But in reality and based on what I have done thus far, will likely be like this: https://www.youtube.com/watch?v=Y-BZQM54QNI
Thanks!
