does not fit my KIA range as stated, KIA and Hyundai use the same engine but have different ones Exhaust manifold , Amazon assumes the same engine should work. It should fit Hyundai. The Kia header has a built in catalytic converter while the Hyundai does not have one so the 90 degree flange needs to fit on the bottom of the Hyndai header, the Kia header/cat goes further down and is already rotating under the engine, eliminating the need/use of a 90 degree rotation on this product
