Great replacement!: Catalytic Converters

Fit was reasonable and fairly easy. Kit does not include additional lower flange bolts and studs. If you are replacing the bottom bolts, you will need 5/16-18 bolts with the same studs. At least in my experience. Also use Walker brand seals. They fit perfectly. Work done on Mazda Protege5

Pros
  • Replacement Parts
Cons
  • Defects

Looks good but has limitations

I bought this item to fix an emissions issue that was causing the DTC to keep popping up. The Revain price was by far the cheapest. Certainly less than a dealer replacement. However, there are a few things to consider. First, the OEM header has studs on the exhaust end. Part #16220 has no studs, just a flange. You must provide nuts and bolts. Secondly, the standard heat shield is not suitable for a new cat. It has an integrated screen that faces the engine but not the radiator. This may not beโ€ฆ

Pros
  • Catalytic Converters and Parts
Cons
  • I don't remember but there was something

Terrible Quality Control

My unit had serious quality control issues.1. Bent pins. Unlike the Mazda OEM converter, this block has pressed-in studs instead of threaded holes. It's ok, you slide it into the manifold and bolt the studs to the manifold with nuts instead of putting bolts through the manifold and into the converter from the top. BUT: One of the five pressed-in bolts was bent about 15 degrees from the vertical. Sometimes the bolt won't push all the way in and you can pull it out again by tightening the nut atโ€ฆ

Pros
  • Catalytic Converters
Cons
  • Not Bad
