I will sell the header and the muffler for $50 a piece...
yeah but the different motors vary in height, and depending upon what motor it is some of them will not fit, it might not line up correctly at the Cat., or there may be a problem involving the Oil Pan and getting it to clear that... Hence why they make the different ones for the different motor. For example you can use a GSR on a B16 but not the other way around, at least for DC sports and other name brand headers. Maybe the no name header's are more universal
