[Healeys] Unidentified exhaust pipe

[Michael Salter]

As I said earlier that is definitely an aftermarket BN1/2 front pipe. The
originals DID NOT have the "waisting" down at the start of the bendas they
were "mandrel formed".
I have had some mandrel formed pipes made and they are quite different from
the Walker type.

These are 2 of mine ... Sorry I don't have an aftermarket one for
comparison.
