Can I put my stock h-pipe on with chip tuned for x-pipe

[MustangLife]

I'm gonna be selling my car. Can I put my stock h-pipe back on my car with a chip tuned for a off-road x-pipe and tuned to turn the rear 02's off. Or will I have problems. My a/f is in the 12's with the chip and x-pipe

Thanks
Josh

You should be able to swap with no issues.

LOL the tunes are a/f and timing determined. It doesn't matter if you put a circle pipe on. The tune wont change.

what do you expect, this is the same guy that says longtubes don't give you any more power on a n/a car. he knows that but doesnt know if he can put the stock H back on with a chip

Whats his reasoning for thinking long tubes don't add power on a N/A?
