Plus I have several good friends that live in NJ and CT with M5 and M6 that has aftermarket Ti exhausts from Japan that has had no issues at all.
I say go for it. Just my $0.02
If this wouldn't be an issue people wouldn't be asking ... One thing when it is made by the factory and covered by the warranty ! I saw many aftermarket Ti systems cracked here and there because of the bad welding, so it is very important to make sure it won't crack. And I am sorry , but you can't compare quality of GT2s exhaust system to Vorsteiner.
