The “Evo-Flow” exhausts are born in the new R & D laboratory in Bologna. They are the result of twenty years of innovative research techniques and experience in the field of modelling of materials, welding and reduced thickness of applied fluid dynamics. All welds are performed manually with TIG technology. The use of gas from within the manifold increases the mechanical strength of the weld itself, does not allow the aggregation of material and makes a smooth and uniform thickness of the pipe, optimizing the flow of the exhaust stream inside. The “Evo-Flow” collectors are made of stainless steel, inconel and titanium. The welds on the customer’s request can be left exposed or polished.
