I think you missed understand my point is your better off tuning a stock engine without headers. Then running headers without a tune which of course when headers are installed you should retune.

Will you state specifically what will be harmed or damaged on his engine if he doesn't get a tune for only headers installed properly with O2s hooked up and working and connected to exhaust piping with no leaks. Be specific. And that whatever that may be that that harm or damage would never occur if the stock manifolds and exhaust were left in place.
BTW I've tuned over 2000 trucks and over 500 cars, many of them running modified exhausts with headers or stock manifolds with no cats for years before bringing their vehicles to me for tuning.

As stated earlier are the reasons if you can't read that then so be it

The problem is, everyone assumes there is only one right answer to a question when, in fact, there may be multiple right answers depending on your particular circumstance.
For the 90% of us that do not tune our own vehicles and of that many a lot of us do not live near our tuners then it is OK to run for a while with modifications untuned if your don't drive like an idiot. If this was not ok then most of us would never be able to mod our vehicles as we have to do it a little at a time as time permits and that doesn't always line up with the tuners schedule.
Now if you tune your own vehicle or live in the same town as your tuner then, yes, you should get a retune after each modification and would be remiss if you didn't.

Oh I see. They yes I agree! Sorry for the misunderstanding
I think the point everyone is trying to make is that you SHOULD retune with a header install BUT you do not ABSOLUTELY have to retune if you do not have access to a tuner right away.
