Are there any aftermarket headers that will fit a G37xs coupe? most aftermarket headers wont fit because of the front drivetrain... any solutions?

 

 

Stillen fit but you have to confirm the build date of the header as they had a few bad runs. As said above, call them and order direct for peace of mind. FI will also fit according to FI but they also require you call and talk to them before they build it so it will fit.
