I'm just trying to remember a name of a company that largely fabricates exhausts, just next to the circuit...
Something.... Primary/Primaries ???

Hi,
I dont think that's the company, as the one I'm thinking of is located about 20m from the track, not 10mins
It's definitely something 'primaries' I'm sure of it.
