Got a question I need some help with. 2003 2.4l - PO removed cat and bolted up short, crappy exhaust pipe. I went and bought a compatible walker muffler and pipe but couldn’t marry it up. So I went and bought a male walker pipe adapter and it didn’t fit. After looking at the parts manual it occurred to be the PO removed the catalytic converter. Not throwing any codes but I would like to figure out a solution that allows me to marry the pipe to the muffler when the cat is gone. Muffler has a 2 bolt flange on it. Thoughts?
