Would anyone want a free set of ARH long tube headers?

I was going to do a dyno run before I get them installed, and I just might do that still, but it's $400 to do that, and I'm having trouble selling the truck I was going to use to fund this little project.
Gonna end up getting way less for it than I wanted, so I'm estimating around september I should have the headers installed. hoping to do a stock dyno run sometime between now and then.

I think they've already designed these with dyno testing.they claim 30ft lbs and 25HP.
I'm not expecting those numbers but I'd be surprised if I hit them lol
I don't think they're going to go for a discount because of dyno results lol

I can say that there are very noticable power gains even without the tune. I currently have cat converter codes because of high flow cats but that will be taken care of with tuning. The most noticeable gains are from mid to high rpm as the truck wants to keep pulling harder.
One thing that I'm not understanding is WHY a tune is going to be necessary when adding headers.
If there are cats, and O2 sensors, then why do the trucks throw cat codes, or what exactly is the issue that needs to be tuned?

A tune isn't really "necessary" if all you are doing is changing manifolds for headers. Will a tune get you more power from the change? Sure, but, a tune will get you more power even if you DON'T change anything else.
And yes, the PCM will figure out something has changed, and it will adapt. Want that process to be faster? Reset the PCM after the header install, and it will relearn the new system a bit quicker.
