Tune for Long Tube Headers?

[jjdelicious]

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.
please advise.

It won't NEED a tune, but a tune will get the most out of them.

If you ask any commercial tuner they will tell you you need a tune because they are financially motivated to sell tunes.

If you ask home tuners or enthusiasts they’ll tell you the truth, you dont

You do not need a tune.

You won't need a tune as the factory widebands can make some adjustments. A tune though will wake the car up 10 fold. You tend to see it a lot in the mid-range too. A tune is always a must IMO.

Let me know if I can help you get setup if needed as we work with all the top tuners out there!
