What's the real difference between the "Installer", "XP" & "Pro" Series exhaust systems made for the CRD? Not being an expert on various combinations of metals/alloys, etc., what's the real benefit of buying the Pro versus the 2 less expensive models? The "Installer" line is made of "aluminized steel". The "XP" is made of T409 stainless steel. The "Pro" is made of T304 stainless steel. I do want whichever one will be the most salt resistant. I'm moving to the coast and don't want the humid salt air to corrode it too quickly...
