O/R long tube question

[89 5.0]

So getting ready to order my lt headers and full exhaust. I was wondering if anyone has had any emission issues with off road long tubes due to the cats being gone? Also will I need to get retuned or am I safe with the stock tune for now?

If your car has to be inspected or have a "sniff test" done for it to be legally licensed then you will run into an issue passing with no cats. Yes you will need a new tune or you will throw a Check Engine light.

Umm emissions here I'm WI is just a plug and play. So I'm hoping with a new tune I'll be ok. Thanks for the info on tuning. I wasn't sure on that!
