Replacing sound deadening and staying legal.
Months ago I began an interior swap (tan for grey) and when I pulled the carpet I found that the original sound deadening had completely lifted and was broken in to chunks, so I just tossed it. Now that I'm modding toward SP to save money and my sanity I realize the sound deadening has to be replaced. What advice can you, the experienced auto-crossers, give me so I can become legal?
One slight detail I left out, I didn't weigh it but others have so I know about how much I need to put back in weight wise.
