I have searched with various conflicting results on this front.

To get to the point, Which Y pipes are the same as what the 2008 G35X has. Do the G37 sedan or 370Z have the same specs on the Y pipe?

Thanks ahead of time for the help.

I know the RWD sedans & coupes use the same Y pipe, wish I could help w/ the X but not sure if all three models are the same
You might email Megan Racing and ask them or Exhaust Depot
