i could be wrong, but i beleive those 'same headers' are equal length headers. not used much in NA apps, but for FI it becomes more of a issue to have all the exhaust from each cyl travel the same distance. i could be wrong, so if someone out there has a better/correct explanation, feel free.Originally posted by Civic_2_NV
people with fast civics always seem to have that same header, looks hot, id love to get a ride in that car
