FWIW, I think SS exhaust is pointless on a Healey, for a couple reasons:
- SS is nice if you drive a lot of short trips, too short to fully boil the moisture out of the pipes to mitigate rust-through
- you could make a Healey exhaust out of titanium, but you will still bash the crap out of it eventually (especially BJ8s)
- as mentioned on another discussion on this forum, your packing will be gone before the metal rots; do you really want to cut up a shiny SS exhaust (and can you weld SS)?
- personal opinion, of course, but shiny pipes detract from the timeless, elegant lines of a Big Healey (again: personal opinion)
My dad bought a Falcon SS for our 100M; I painted it black. It sounded tinny at first, but has mellowed with age. I only have a couple thousand miles on it, so can't attest to durability. Also, one of the English suppliers has a mild steel, 'Big Bore' exhaust. Whether or not it offers any performance improvements I couldn't say (probably only with headers).
