TODA Exhaust System 2006+ Honda Civic Si 4 Door (FD2)

TODA Racing USA has concluded our test of the exhaust manifold and exhaust system orignally designed for the new Honda Civic Type-R (FD2) chassis. American spec Civic SI features a shorter catalyst compare to the Japanese Civic Type-R, which is un-heard of since any Honda enthusiasts that owned a B-series from 1990~2000 would know it was the opposite. Some of the significant difference in chassis/exhaust hanger designs are listed below. Since the factory catalyst in longer on the Japanese spec FD2 Type-R, which means the B-pipe after the catalyst is significantly shorter. Consumers would have to purchase both the exhaust manifold and exhaust system together if they intend on using TODA exhaust on their American spec Civic SI.
