i guess that's where they got the name for it? so let me get this straight.... the stock jdm it-r 4-1 exhaust manifold (almost equal length), isnt an exhaust manifold? its actually a header? is the it-r 4-2-1 a header or exhaust manifold? but the 4-2-1 looks like the stock one on my accord... which im sure is an exhaust manifold... i bought a GReddy header 4-2-1 for my accord, and its def. not close to equal length. So should GReddy call it a manfold? i do have a dc header for my civic (4-1) which is almost equal length.... blahblahblahblah.....
