I think it’s the cat(s). Any thoughts on aftermarket? Normally, I’d go for the best/oem but it’s very expensive, and I don’t use this vehicle much. I considered getting a cheap aftermarket set and then attempting to clean the existing ones. I figure if I can unclog them via cleaning, I’ll save ’em for when the cheap ones give me any issues.
