EXHAUST
421 EXHAUST MANIFOLD
Developed in response to demand for a balance between peak
power and torque. Spoon implemented various combinations of pipe diameter,
assembly rotation, and other similar factors in exhaustive engine-bench,
flow-bench, and actual-driving tests. The power and torque were successfully
balanced and using slightly uneven lengths for pipes, further reducing
considerable weight.

2 IN 1 EXHAUST MANIFOLD
For power and balance, a 4 in 2 layout be adopted to exhaust manifolds
for B16A, 1,600cc, 263mm block-height. The clever design of the interior
of the 2in1 genuine part product ensures that a wide torque band performs
well over the range of practical driving speed. This manifold is highly
recommended for use in races. Please note that exhaust manifold replacement
often leads to a loss of torque in the low speed range, and the cause
of this usually is using other inferior aftermarket parts.
