Hi, new to the forum but need a little insight. Recently did hi flow cats and a flowmaster 44 exhaust on my 04. I replace the o2 sensors as well. Getting lean and rich o2 codes on bank 2 now. I have long tube headers and a mopar cold air intake that were on the vehicle when I purchased it in 2018. The cats were making a ton of noise and the truck was losing power at times which is what made me make the mods. Anybody have any insight on my problem? Would be most helpful.
Thanks in advance
