This competition exhaust manifold is developed based on data acquired from competition and continual engine dyno bench testing. It is designed to extract every bit of horsepower from a modified normally aspirated K20A engine. With increased power output through out the entire rpm range, this exhaust manifold improves both midrange and highend power.

Constructed entirely from high grade stainless steel for long term durability, TODA exhaust manifolds are hand built by experienced craftsmen at the TODA factory, therefore available quantities are low and you will not find one on every other car out there.

An auxiliary oxygen sensor port is built into to every header to allow for fitment of lambda meters and air/fuel ratio monitors. This will allow for precise tuning of engine management systems and fuel control devices.
