My grandparents have a Mazda Millenia, pretty sure it’s a 2001. It just failed emissions and Mazda wants some incredulous amount to replace the cats.

Anybody have experience with these and have any better solutions?

thought factory had to warranty acts for 10yrs or 100k?

if not i can put some replacement ones on. doing a benz tomo and factory wants 2k for these. so making these ones up and replacing them with aftermarket.

I’m not sure how close up to the headers they are, but I can take a peek.

They’re under 10yrs, but over 100k.

The generic ones work. I put one of these on my Accord (173K miles) this month and the car passed emissions.
