will an 99si header fit a 99gsr motor?

it will but you have to use the civic catalytic converter. But if you have an Si header lieing around and you want to use it to save cost just go to a muffler shop and have them make you up a straight pipe to connect it to your exhaust.

I guess I was just one of those flukes then cause I used to think that all b series headers would fit, but I just did a C5 swap and my DC headers won't clear the bottom, so I had to take the stock headers off an ls to use for now
