Whatsup every1...i just joined the forum and i was hoping some1 could help me. I just bought a 1994 civic si with an ls in it. Right now it has a full dc sport cat back exhaust but its running off of the stock integra manifold and downpipe. I want to get a header but im not sure whether or not a regular b18 integra header will fit the civic chassis or not. Does any1 know??
