Thanks for more mixed views...
@ Chuff. I know a bit about it, I wouldn't have chosen it. The system including manifold is Supersprint
but for some reason in the 90's the rear box was changed for one by Magnum Tuning.
Previous owner raved about it, they were a small company based in Europe that could make your exhaust on spec, sound type, db levels, restrictiveness etc. I believe this is a one off.
Although still made in Europe the company is based near Daytona or somewhere like that now. TBO it sounds amazing, old boy down the road has nicknamed it the spitfire.
I might change it (but keep it) when I'm feeling flush.
