problem with ls header fitment on 01 gsr
i tried to install a ls header on my 01 gsr which should fit. But after bolting everything up the collector on my dc 4-2-1 header with the donut gasket doesn't seem to fit in the cat. It seems like the flanges are off a little the bottom of the collect fits but the top doesn't seal.
