I have not had time to fit it yet, and my patch is holding up fine, but on my recent GWNF trip the exhaust broke off on the way down. I just removed it for the rest of the trip, but when I got back I sleeved it with some slightly larger exhaust pipe as a temporary measure. But the rest of it is looking pretty rusty and the root cause of the failure was a hanger breaking, so I decided to get a complete replacement system and splurged on a stainless steel one (which hopefully will never rust out).
