The "High Flow" cats that you see on ebay are cheap because they do not always have the proper elements inside to do their full job, compared to an OEM or quality aftermarket cat. Catalytic converters use very expensive/rare metals in the honeycomb element located inside the cat in order to do their job. I don't know the exact science of how they work, but that's why a real cat is so expensive. The "high flow" ones have less or none of the element inside. You get what you pay for
Also, 25,000 miles is not much of a warranty. Heck, in Ohio, cars are only required to pass e-check every other year. Average person drives something like 14k mi/yr. You wouldn't even know your cat failed until 2 years later when you go back in for emissions check and your car fails emissions. The OEM cat on my hatch is 20 years old with 180,000 miles and my car passes factory emissions at e-check... WITH a turbo!
You get what you pay for, so if the one you can afford comes with a 25,000 mi warranty... might as well get the cheapest one with that warranty since I don't see it lasting too long.
Do Not PM me your technical questions. Post them in the forum!
