I have the F.I TDX w/ 18" resonators. On cold start, I become my neighbors alarm clock, lol. It quickly calms down after about a minute or so though. I get some drone at around 2200 RPM, but I am usually not in that range for long while crusing. Only in stop and go and just for a moment. That is how the NISMO should have come from the factory IMO, but I also loved the way the Z33s sounded and they were much louder stock in comparison. Soon I will have a custom TDX for use with my TT installation. That should sound pretty awesome.
The Ark sounds great from the vids and such. Haven't seen one in person yet though.
