K20A (FD2) CIVIC TypeR
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 K20A engine but also the results of an extensive bench testing program.
-The standard catalyst can be installed, when TODA high power muffler system and TODA optional short front pipe are installed. (Instead the rear pipe of TODA header can NOT be used.)
-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.
-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
