Cut it out, but I'd hang onto it, for emissions purposes . No check engine lights either

Pro: Better flow

Con: I can't think of one, unless you have to swap it back in for emissions, like me

You should not have to cut anything. Just loosen the band clamps and spray with WD-40and with a little work it will come off. But I'f your putting a complete system on you can save all the original pieces without cutting anything and store it.

Yup, take it off or gut it out. I gutted mine so if I get pulled over, I have a cat in case of a visual inspection.
