- The ideal header for maximizing top-end horsepower. Perfect for All-Motor Drag Race applications. Also recommended for supercharged B-series motors.

- Features large 45mm (1.75") diameter CNC mandrel bent primaries and a huge 2.5" collector outlet.

- This header will not bolt up to stock Honda/Acura catalytic converter. We recommend using our J-SPEC Header Outlet Flange kit (Part #2599) to make it easier to connect this header to a catalytic converter.

Please Note:

This header can be installed on all 1994-2001 Acura Integra models (LS, RS, GS, GSR, Type-R) but will require modifications to the factory catalytic converter to fit properly.
