Here's some sounds I took, the video is showing first (with all windows open) idle, light acceleration,medium acceleration (header tick) & finally WOT. Keep in mind I have no secondaries and an X-pipe in place. CLS stock is louder than e55 so expect maybe a 30-40% difference between stock setup and mine on e55 with only headers, I also have a 77mm which makes it louder too! Last bit of the video is WOT for a little bit with all windows up. I'll try get my mate to do some drive by videos tonight so you can hear the full glory..
That's a shame about being imported so recently. I believe that anything registered pre 2011 in NZ doesn't have to have any Catalytic Converters at all. I think since you're removing primaries only most WOF places won't notice, especially since the secondaries are still there and most cars only have 1 set of cats. At worst you'll just need to find some Asians or a dodgy place. I have one in CHCH who barely looks at the car but costs 60 bucks lol.

Thanks for the videos. I will have a list on the computer tonight. I will keep the secondary cats. If they have an issue at warrant of fitness time I assume they would be ok with upgrading the secondary's to a full size set to solve the problem. I would be ok with doing that. I usually get WOF at the dealer.
