ScienceofSpeed Factory 1997-99 Header Adaptor Kit for 1991-94 NSX

Some customers wish to install the later model tubular factory Honda NSX exhaust manifolds which in 1997 were introduced to allows the car to flow better.

While the factory 1997+ exhaust manifolds do not flow as well as aftermarket header designs such as these, the factory exhaust manifolds can often be found used at used prices. The adaptor kit includes pipes, crush washers, gaskets, and hardware. Please note: the 02 sensors extensions shown are available separately here.

This kit allows the 1997-99 headers to be installed onto a 1991-94 NSX with out modification. Pipes bolt to existing 1991-1994 catalytic converters. Factory 2000-2005 headers would need to be modified by an exhaust shop to work with these adaptors.
