Toda Racing F20C/F22C (AP1/AP2) TODA Standard Exhaust Manifold (4-2-1 SUS)

In order to get the best performance, engine power, efficiency, this exclusive exhaust manifold design takes into consideration not only the special characteristics of the F20/22C engine but also the results of an extensive bench testing program.

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.

Racing high flow junctions design
Each section of the manifold has optimized pipe lengths, diameters and angles as well as high flow junctions.
