F20C/F22C（AP1/AP2） S2000
TODA Exhaust Manifold
(TODA Standard vs. "Torquie-kun")
Note : The high efficiency of the original TODA Racing Exhaust Manifold for F20C has more than proved itself as a competition product. With continual development we have now released an alternative version. Above is a graph of the standard TODA Manifold and "Torquie-kun" after bench testing. The graph shows a 3 H.P difference at max power in favor of the TODA standard manifold (RED), and a fuller torque and power curve from Torquie-kun.
S2000 Testing TODA exhaust manifold
Designed competition purpose for TODA standard exhaust manifold was increased more torque in a practical range.
A bench test (Equal length 4-2-1 + Taper) design
Ø45mm → Ø50mm → Ø55mm → Taper → Ø60mm
*Taper design is adopted from feedback from both racing and the bench testing.
*The 50mm diameter part of pipe in middle was extended length properly.
Racing high flow junctions design
Each section of the manifold has optimized pipe lengths, diameters and angles as well as high flow junctions.
With the service adapter for A/F sensor
Made of light weight stainless steel for both durability and looks
Flange manufactured by high precision machining center
The standard catalyst can be installed.
