No idea of the sound, at least without the multiple extra rust holes.
When I opened this one, I couldn't believe it
I also have a drawing of another exhaust built by a former Bagheera owner.
It was quite interesting because the exhaust could be disconnected easely from the 4 into 1 manifold to allow works. Also the part holding the silencer (actually the standard plate) was located mid way of the silencer.
I'll try to find this back
