Long tube headers and no tune?

[RubyRed PP]

Selling car and trying to go as stock as possible. The only thing that I can’t go back to stock on is my Stainless Power long tube headers.

Can I run this with the stock tune? It has cats and all 4 oxygen sensors.

It will run poorly most likely and or throw codes.

What does everyone else do when selling their car with long tubes? Keep the tune on it? Even for a trade in at dealer?

I came across my headers this way. My friend had to trade his Mustang in. He didn’t want to pay to swap them, so I swapped in stock manifolds and kept his Texas speed for doing it. I also had to buy him O2 sensors. But basically I got his headers for 70$ and a few hours of my time swapping the headers for manifolds. His car wouldn’t run very good at all when he took the tune off. So in this case if you can’t get anyone to swap them I’d just leave the tune on.
