I'm having trouble locating a two piece 4-2-1 exhaust header which would clear the bottom of my B18C1 and be the longer pipe as seen in the 00-01 GSR. It must be 4-2-1 and two piece as nothing else would reasonably fit my setup. Any recommendations? Right now I've got a cheap ebay one made for a B18B1 and it doesn't clear the oil pan, though I did some real ghetto temporary fix for now...
