Honda S2000 K-Series RWD Sequential Tri-Y Exhaust Header
This Exhaust Manifold features 5 step piping size with each step helping in anti-reversion, and also backing up of exhaust flow. Weighing at 12lbs less than stock (OEM is 25lbs), the primary runners are 1.75 inch, to 1.875 inch, to 2.00 inch, to 2.25 inch, to 2.5 inch merge collector. Stepping the header pipe size helps direct flow and increase scavenging, thus allowing for a faster exit.
The K Series firing order is cyl 1-3-4-2, therefore our runner design is sequential, creating a venturi effect. Wheel horsepower gains are approximately 10whp mid-range dependent on application setup.
This header is made to fit K20 or K24 Rear Wheel Drive RWD applications. For S2000s it will mate perfectly to the stock S2000 catalytic converter.
