Review on Dorman 673 642 Integrated Catalytic Converter by Derick Carpenter

Revainrating 4 out of 5

Best for my 2004 IS300 Catalytic Converters and Parts

This converter fits no problem however the bolts that come with this system are not tightened. For some reason these nuts were oval shaped and would not tighten past a certain point. I ended up using my standard screws which worked great.

Pros
  • Replacement Parts
Cons
  • Mystery
