I've got 40's on my coach. I think they're too noisy and even more importantly my wife doesn't like them. I've been thinking about changing them out. I was under my coach and found that the aluminum body panel above them was cooked and distorted. Flowmaster makes heat shields and after sucuring the aluminum panel back up, I'm to install the shields. I've read that they reduce the noise. I'm hoping they do, but probably not that much. I was thinking of putting a piece of lead sheet between the shield and the muffler for further sound reduction, but looking at exhaust temps and the melting point of lead, thought better of it.
