Judge Posted January 26, 2019 Share Posted January 26, 2019 (edited) Looking at various exhaust manufacturer's websites, the part number is the same for the 350Z and 370Z Y-pipe (ISR is an exception because it uses 2.75” primaries for the 370Z). Does anyone know if the Motordyne XYZ with resonator module is also interchangeable between the 350Z and 370Z? I've looked on the Motordyne website but it's not clear. I've also looked on various trader's websites and on some the part numbers are the same, on others they're different. Does anyone have any information regarding power / torque gains, preferably with dyno charts? I can't find any information on the Motordyne website and the only other information I've been able to find is shown below. There are other threads on various forums but they're so old the images of the dyno charts are no longer there. XYZ Gains 1 XYZ Gains 2 Thanks.
