4AG (AE86) LEVIN, TRUENO
-4-2-1 Ver.2 strengthened
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.
A bench test (Equal length 4-2-1 + Taper) design
Ø45mm → Ø48mm → 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)
Standard catalyst can be used
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.
