SD Tec exhaust

I have found a site, Oficine, selling stainless Lafranconi copy exhausts for the Le Mans 1 and 2. Anyone have any experience of this make. Are they any good? Are they too loud for road use?

Thanks.

Suggest you share a link to the site in question, Steve, so people can recognise it if they have first-hand experience.
