I spoke to them on the phone today and they said that the Y-Back for the sedan is on back order till the end of next month. In addition, they said that it's doubtful any of their partners hold stock as they have been waiting as well. They did not know that Manzo made an exhaust that looks virtually identical: Infiniti G35 2007-2008 4DR / G37 2009-2013 3.7L VQ37VHR 4DR Sedan RWD Stainless Steel Catback Exhaust System Version 2 (w/o Y-Pipe)

But they did confirm that their systems are prototyped in the US, but built in Taiwan.
