It may have a shorter warranty than the factory but that's not proof of anything, so long as it's stainless. Lots of car parts don't have long warranties even though just as good/long-lived as OEM factory parts. I expect a large part of why the warranty is short is the risk exposure level, that they're selling it to be put on a vehicle that already damaged the original and will probably have more and more oil, coolant, fuel finding its way out the exhaust over the coming years compared to the first cat's tour of duty.
Why is any OEM part typically 200%+ the price of an aftermarket? There's definitely not > $100 more precious metal in an alternator for example...
That's just how the market is set up.
Those $300 specials perform as well new as the OEM ones do at end of life. They are literally just active enough to get a pass with no margin for lifetime/degradation. BTDT.
No thanks... If the car is worth keeping, do it right. If you can't afford to do it right, get a bus pass.
