Review on MAYASAF Catalytic Converter Corolla 2003 2008 by Shane Solorzano

Works on 2003 Toyota Corolla but not quite. Do not look for instructions as they will not come with your purchase. To install you will need to cut the pipe between the cat and the resignator, I cut it 1 inch past the cat. Without a micrometer, it turned out that both the old and new tubes were the same size. I figured I would have to weld them together to install them. You can use a butt splice and clamps if you don't know how to weld. However, I managed to fit the new hose into the old hose, which was quite tight, and then I pinched it. (Hopefully notice cracks). The cat itself fit, but the equipment didn't. The included clamp is 2" while you need 2 1/8". The flange is properly aligned, but the gasket is larger in diameter than the pipe coming out of the elbow. The gasket seems to fit properly into the flange (fingers crossed it seals) and the two spring bolts keep everything in place. The gasket just isn't the same size as the one that came from the factory. Speaking of spring bolts, but they don't fit and don't work. I had to reuse my rusty originals. Fingers crossed it will pass the emissions test.
