The NA Sports Feel Has Evolved To An All New Level.
The 1st Version design had the targets of “Sharp throttle response”, “Sports engine enjoyment” & “True race exhaust sound”. This new version 2 design has all those target aspects met with the additional target of increased power gains. The designs were made and time painstakingly tested both on the engine bench Dyno in a controller environment and on the car in real life uses in the Z Masters race series in Japan. With these tests we found to have excelled in additional performance gains from the previous 1st Version model.
NOTE: These headers are built to be a direct bolt on to the VQ35DE, however they can be used on 07+ VQ35HR and VQ37VHR engines with the use of Stock DE Catalytic Converters.

These headers can also be used on 370Z and G37 models, however use will require exhaust manifold studs be moved to accomodate the header flange. This only works on earlier models with holes pre-drilled for the alternate stud location. It appears that after 09/10 production cylinder heads were no longer pre-drilled for alternate stud locations, Z1 cannot guarantee fitment on models manufactured after 09/10. DE test pipes or High Flow Cats (linked above) will also be necessary for installation. Will not work on AWD G37 models.
