Res and rear box delete

[Neaky290]

I am due to have the res delete on my 290 next week but I was wondering if anyone has done the back box as well?
I've heard that they drone a bit but that doesn't bother me too much.
What I wanted to know was how loud they are and if its a good exhaust note with both done?
Thanks
