I want to put the lude on a bit of a diet now I have my new motor in

It's my DD so I'd like to keep some refinement like seats and dials but want to get rid of some of the other stuff and eventually get onto the CF stuff (when I pull my finger out

After that was thinking of removing the 4ws, anyone have an idea of cost and time along with weight saved? Also, my cruise control doesn't work anymore so thinking of taking that out too...
Also, with the sound proofing taken out is the noise level in the cabin much higher?
