After many request from our racing customers, the racing look springs have been removed to give a simple look, but retaining the same specification from the first model.
-The reinforcement plate is added
The reinforcement plates are added to each racing junction and a head plate to each pipe exit. Improved durability.

Ø45mm → Ø50mm → 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
(Flange exhaust port diameter:Ø38mm)

Original 2000 version of the 4-2-1 design. For ultimate power the 4-1 type exhaust manifold design is the one to use basically. The problem is that power is only made from 4,500 rpm in the process removing drivability. TODA racing have designed a 4-2-1 system which restores drivability 15% more torque* with only 1.5% loss of power*
*TODA 4-1 bench testing manifold used for comparison.
