Do i need a tune w/ muffler delete

[BlueBoost]

Hello, I have a 2017 mustang ecoboost and I'm planning on taking out the mufflers and running pipes to the tips. Will I need a tune after doing this? Or will the ecu adjust for the reduced back pressure? I really want to make this car last forever.

You do not. My brother did a muffler delete and other than that he is stock. Been running for 10k and no check engine codes

Just watch out for cops. In about 90% of the USA, this violates local and/or state noise ordinances I know for a fact in Texas repeat violations will get your car impounded and release from said impound will require you to do something to silence the exhaust...

I really hope one of these days we get rid of the "Back Pressure" thing. You dont want back pressure...

As long as you leave the bearings in place, you'll be fine.

The upper or the lower bearings?

Upper. The lowers are just a placeholder and don't really serve much of a function.
