Help with Identification...Is this an MX5 exhaust?

[ClueLe55]

Could anybody tell me if the exhaust in the picture is from an
MX5. If it is it would be from a BBR Turbo model.

The alternative is a MGB.

It is a shame that I am so clueless, but it has been in storage
in the loft for ages.

Thanks for your replies and pictures folks.

I have scrolled through hundreds of adverts, articles and webpages
trying to find a match, but I cannot find anything with the shape
of my exhaust. I will have to keep on scrolling :-)
