They both have a fair amount of discussion of exhaust systems, mods, etc... and I haven't seen any mention of 49 states.

However I would wait for one of the experts to answer, but my best guess would be no.

Thanks for those links. I can shop while we wait! I've been wondering why I see "Bentley" in some of the posts. Now I know!
