Good day all I had recently posted a post on a problem I was having with my brakes but it all sorted now. But I wanted to post on another problem I'm having with my 2010 Subaru Impreza 1.5 awd gh3. The car has 120k on it but a year ago I had to decat the catalytic converter and run straight through the exhaust where the cat was because it was broken up inside and rattling inside. But after doing that my fuel economy fall drastically. I get like 17 mpg and I run it like this for a year, but I want to get it fix now. I don't know if it could be the o2 sensors reading wrong because not cat or they just bad. I don't want to replace them if they not bad. If anybody know anything please give advise
