Hedmans race plant is in either N.C. or S.C., they offer kits of bends of both sizes you need and they also offer either flange kits with welded stubs or plain precut flanges Summit also sells bend kits, check around for what you need. I ended up buying all the parts from Hedman through Summit to do two different cars, one with 2 inch kit and a 2 1/8 kit to make them step to a 3.5 inch collectors and the other is from 2 1/8 to 2 1/4 primarys into a 4 inch collector with welded 2 1/8 stubs I had Summit have Hedman drop ship all the the part to me direct Not cheap though, shop around first
