PreCat Exhaust Question????

If somebody guttes Out the PreCats is it samething if u go and pay $500 for PreCats. Or if you replace it, would it give you more air flow and turbo spool up than if your gutted????

Thank You

If you mean $500 for precat eliminators...they are a bit better in flow than simply gutting them...however it is free vs. $500. End result being nearly the same.
