I think FXMD should do the one for OEM position fitment as pretty much 70% of the NSX owners here are running dual exhaust and I'm sure most of us are happy with what we have rite now (like sound and out look). Look at Oyagi, he has been waiting on the list almost the same time as me....now others are out once we know FXMD will only make the one for center exit exhaust. To be honest, how many of us are willing to use center exit exhaust?
Oyagi may be out because he's selling his car.
As the one who originally conceived and put this idea on Prime years ago, I quickly realized the center exit exhaust would be the only way to go. Unlike a real Scuderia where the muffler is up higher, on the NSX there just isn't much room underneath the trunk to have a side exit exhaust and a functional diffuser. The muffler has to be in the center in between the diffuser fins.
