Our header adapters allow you to use factory or aftermarket 97-99 NSX tubular exhaust manifolds.
While the factory 1997+ exhaust manifolds do not flow as well as aftermarket header designs such as aftermarket full tubular headers, the factory exhaust manifolds can often be found used at used prices. The adaptor kit includes pipes, gaskets, and hardware. May require O2 sensor extension wires.
Our kit allows 1997-99 headers to be installed onto a 1991-94 NSX with out modification.
Pipes bolt to existing 1991-1994 catalytic converters.
