Hi All Can we differntiate between "rust" per se (ie corrosion that will one day lead to the failure of the product) and surface oxidisation, which tends to occur even on stainless steel systems, and is unlikely to cause failure. The UK system comes with a lifetime guarantee and is made from 304 stainless. Although you would be responsible for removal/refitting in the event of a problem. This is the nature of the motor trade :-( FWIW I recently read a similar gripe on the Alpine forum from someone who had fitted a free-flow stainless system for a GTA Atmo from Mecaparts. The manifold cracked after 18 months and was not covered under warranty. I'm looking into using the DeLorean manifolds from stainless-exhaust.com and supplying to the Alpine community.
