Toda Exhaust Manifold - 06-11 Civic Si

TODA 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 engine with attention paid to improving power all over the powerband.

Originally designed for the Japanese spec Civic Type-R (FD2) chassis.
