JD1, I don't have the exact experience you're looking for but it's very likely someone here has gone down the path you've described on exhaust systems. If so I trust they'll chime in. That said, there are decades of great information here that does get overlooked as we look for instant answers. I'm a believer is using the search button. However I do find myself asking questions when a few minutes searching would give the answers I'm looking for. When that happens I feel a little embarrassed since I often wonder why, why, why didn't I look first.
Good Luck,
