If you are running the factory catback, headers sound great with it and honestly what I recommend to most. Adding a resonator delete is the only other thing I would say can help but ye it will make it louder. We came out with this resonated H-pipe to help. keep tame the sound with headers and...

Yes sir. They use the factory clamps.

So if you go with headers, you can install and go. This is for catless or catted ones as the front widebands can adjust. Now with catless, you do run the risk of a CEL. You can go with 02 mini cats to help mitigate the chances but no promises. If you go with cats, you will need the ones that...

Simple answer. It's illegal to have fuel and oil mixture to be stored outside of a motor so it's an EPA thing. This is why on some of Fords manuals, they suggest you add one as they can't new.

So the motors are still the same as prior years with the PCV. It pulls air from the driver side into the motor and out the passenger side. The drive side will mostly stay dry unless you have a lot of blow-by. Doesn't hurt to have though...

We run KOOKS on ours and they have been good. I have used LTH Exhaust headers in the past and swear by them for fitment and with collector design and location, it can deeper the tone a little. With the cats, as long as you go with the GREEN from Kooks or the EcoF from LTH, you will be fine. The...

Sadly as of right now, Ford Performance has no time frame or evidence of a GT FPP Calibration. Hoping this changes though.

Yes we do. Send me a DM and we can get a quote for you.

Honestly the sound will be the only difference between them. And the muffler will affect the sound as well. For the Double x or H versus regular, it tends to get rid of any drown that could come from it. The biggest thing to take away is sometimes the cheaper ones will use thinner sidewalls...
