tune required

So I have Texas Speed Catted Long Tube Headers for my 2015 mustang gt. I have a corsa extreme catback exhaust and a K&N Drop in filter. The car is STOCK. i was wondering if a tune would be required after installation. i’ve read that you don’t need a tune because it comes with O2 Extensions...

A few questions…… My 2017 stock intake manifold made it 65,000 miles before it cracked :/ stock 2017 intake manifolds are backordered beyond oblivion. Been waiting 1 month already. Looking at a 2018 intake with a lund tune. My powertrain warranty is well expired so the tune should be fine...

No longer for sale.
