ScienceofSpeed High Flow Catalytic Converters

High flow direct replacement catalytic converters for the three exhaust year generations, 1991-94, 1995-99, and 2000-05 using high quality federally approved .

T304 stainless steel, TIG welded tubing, converter bodies, and rod. High quality catalytic converter cores are rated for 420+ CFM per catalytic converter, or 840+ CFM total. The factory NSX engine naturally aspirated flows approximately 398 CFM and 675 CFM supercharged & turbocharged at < 9 PSI of manifold pressure.
