I got a 2015 Mustang GT PP, Borla 2.5 inch Catback exhaust on my car right now. I have a 2018 Intake manifold sitting in the garage along with a 2018 K&N Cold air intake. I was looking at getting some Long Tube Headers before I get my tune. Install it all at one time. Tune one time. How much of my Borla exhaust will I be able to use. At what point do injectors need to start being upgraded?
