Alrighty i have the DC sport 4-1-1 header and wondering since they look really whimpy and short and didnt really feel that much of an increase. But has DC sport came out with a 4-2-1 header? Because i was on this site http://www.dezod.com/cat_civic_0103_headers.cfm and it said they have, but sometimes sites are wrong and i was just curious if anyone has it or heard anything about?

and the second part ive seen some posts on the HP header. it looks huge, what are some peoples opions on it and wheres a good site to look at them? and does the down pipe make a difference with it? if u could give me some feed back that be nice thanks

A header won't really give much gain on our cars. Neither will intake and exhaust. If you want more info on the HP header, PM Ironfist. He did a review and install of the top portion.

4-1 headers give gains on the high end. 4-2-1 give low to mid power. But I have never heard of a 4-2-1 header for our cars. The only way a header will help on our cars is with nitrous. Turbo, ur replacing it anyway...

HP Racing header comes highly recommended. Header with downpipe and cat replacement @ thecivicstore.com for $280. Thats my next move.
