Ok I got a gsr engine in a 1999 civic hatchback, got a magnaflow exhaust and I got a turbo header. My problem is I need a (I guess it's called a ball flange, standard for hondas hooking up the rest of exhaust to the header) that is 2.5". I have done a lot of looking around on the net trying to find one. To this point no luck. The one on the exhaust now is 2.25" which just isn't gonna work. Anyone know where I can get flanges like this. What does everyone else do, do they cut off the flange at the header and put a more standard flat flange with a flex pipe added on. Or is there something else that I'm missing. I ran into this when I was originally hooking my DC header into the stock exhaust, the dc header had the same deal with the donut gasket and the ball flange for the exhaust side. The magnaflow exhaust works on that because luckily it was the same size, but now that I'm going turbo I need one bigger.
