As topic states
Does a brand new cat-back exhaust need to be broken in?
If so how long and under how many RPM's?

Not only does it carbon up, but the catalyst in the converter loses some of it's
efficiency. The catalyst just changes carbon monoxide and ?forget this one? to air and water.

I had just a universal muffler at one time, and after about 8 months it was very loud and boomy, whereas when I was first got it was loud and boomy but I could at least drive on the highway with it.

The sound will change a little over time, and you should have some new smells after it is installed for a bit too.

Will a stainless-stell-packed muffler thin out and become louder over time?

no you dont have to break it in.. just drive as you would... you'll notice some smell.. kinda a burning smell for the first 100-200 miles or so (at least i did on my Greddy cat back)..
