Engine
bench testing & actual racing
Exhaust manifolds manufactured by TODA racing are
used in competition. Ideal lengths, diameters, and
shapes are determined using feedback data from racing
and continual engine dyno testing. The highest grade,
lightest weight stainless steel materials are used
to manufacture TODA exhaust manifolds. Experienced
craftsman meticulously hand build each exhaust manifold
and exhaust system, therefore production volumes
are low. |
Ideal
4-2-1 design
For ultimate power the 4-1 type exhaust manifold
design is the one to use. The problem is that power
is only made from 4,500 rpm in the process removing
drivability. TODA racing have designed 4-2-1 system
which restores drivability 15
% more torque*
with only 1.5% loss of power*.

| As
used on all the latest 4-cylinder racing engines
the 4-2-1 gives best result. |
