2004 Saturn Ion catalytic converter

I need to install Cadillac Converter in my Saturn. It’s a universal kalak converter is it very difficult or what? Do I have to remove the whole? Pipe.

Since you mention “universal” that makes me think we’re not talking about a direct-fit catalytic converter

If I’m correct, that means you’ll have to cut out the old cat and weld in that universal converter

Do yourself a favor and make sure what you’re planning to do is legal in your state

If your car happens to have california emissions . . . very common, even if the car initially sold in that state . . . several states require the owner to keep the car california-spec compliant. This particularly effects catalytic converters
