Morgan didn't solve yet - as far as I know - the issue with the M3W Brooklands exhausts.

That's disappointing if true. I'm about to get new exhausts and my dealer told me they were upgraded.
I guess I was lucky I got almost 6k miles out of my old exhausts before they (both) broke.
By the way my Brooklands is #42.
