I'm seeing prices at Rock Auto for a replacement cat between $150 and $340 USD. My local autoshop was quoting me $900 CAD + labour. So am I correct that's a significant mark up? Just wondering if I'm looking at spending a grand on replacement or not.
Not sure if it's the pre cat or the final cat that is the issue at this point. Had a rear 02 sensor replaced and then got a new code about cat efficiency. I'm thinking it might be the first catalytic converter, the one on warm up, that's the issue but can't say for sure at this point. I know the car likes to rev to 1500 RPM upon start and then climbs down to a resting 500-700 RPM after about 4 mins. Is this because of the two catalytic converters?
