The ScienceofSpeed Advanced Exhaust Headers are the result of years of testing to develop the highest performing exhaust header for the NSX using superior materials and craftsmanship.
designed, tested, and manufactured by ScienceofSpeed:
The NSX transversely mounted engine produces a number of design challenges. Several designs were developed and tested - the result is a design that features equal length primary tubes, high flowing merged collectors, and a fit and finish that is guaranteed to be factory perfect - because new factory exhaust manifolds were used to produce the jigs that these headers are built on.
The ScienceofSpeed Advanced Exhaust Header System features no-compromise quality. Each tube is manufactured from 304 stainless steel and is mandrel-bent by computer control to maintain exacting tolerances. Tubing is TIG welded with each runner back-purged with inert gas during the welding process. Where other manufacturers use less expensive mild steel for flanges, all ScienceofSpeed Advanced Exhaust Header flanges are cut from 304 stainless steel.
The final production headers have been independently tested using a protocol developed to exactly gauge and measure performance results. Factory original NSXes were baselined on a chassis dynamometer with sensor feedback normalized. Back to backtesting was then completed on the same vehicle with the sensors set to the same normalized feedback. Testing runs were then repeated and mean averaged to eliminate any variable deviation.
