Makes it Louder: Catalytic Converters

I really like these Flowmaster High Flow cats, they have significantly increased gas mileage but I have two downsides. First, it keeps reporting my passenger side O2 sensor as bad but not the driver side. Second, my engine's temperature rose almost to the point of overheating. I cut them off after only 150 miles and weld them back to my standard crampons.

Pros
  • Good Stuff
Cons
  • Style 90
