So basically, my car needs a new Catalytic Converter. The question is, which cat to get and would i need to do any tuning if I get a cat other than a stock type replacement?
I'm looking at getting the PFYC.com High Flow Catalytic Converter with the 3'' inlet and 2.5'' outlet. Has anyone bought one of these before and would I need to do any tuning to the car to make it work? I don't have any tuning software/hardware so I want to be sure that whatever I buy would work by just installing it.
Any help with is appreciated. Also any advice for other possible replacements is good to. I'd prefer the cat to work the same, or better with no computer modifications needed. Thanks for the help!!
