Exhaust
Googled a lot of searches and always came up with something being deleted. Im
assuming if you straight pipe these trucks it voids a warranty? Or the whole warranty?
I was was looking at mbrp exhaust because I love that turbo Whistle sound. Just curious if it's obtainable without harming the warranty?

Also, I'm pretty sure a post DPF/SCR muffler change would be fine. Deleting anything would definitely void its warranty, and could have ramifications on your power train.

It would be Ford's burden to prove that your exhaust caused a failure. However, I don't recommend removing emissions systems from these trucks unless you are out of warranty.

Also it won't be ford's burden to prove anything, it will be yours. Ford will tell you too bad and you will have to prove what you did didn't make whatever went bad go bad. To them it is a simple yes or no to warranty stuff and they aren't going to think twice if they say no because you changed something that effects the engine and you have engine issues. You will be fighting Ford for the warranty work.

Changing the muffler will do very little to nothing at all to the exhaust note, you have to take off the DPF to get a better exhaust sound and as of right now I don't believe there is a DPF delete tune out for the 2017 yet.

Changing muffler should be fine but it might hurt the actual power of the engine but probably only a little bit that you won't notice. These engines are tuned with the system they come with in mind. If you change air flow in/out then to achieve the best results you should tune the engine for the new system.

That being said, while unlikely, if your turbo dies after you remove the exhaust system, it's a pretty safe bet Ford will rightfully deny your claim. I will not be deleting anything from my truck, as alimony getting ESP.

If you remove the DPF, expect that your warranty WILL be voided on the entire engine, exhaust, and emissions system. Likely the transmission and many other parts too. Sure, Ford has to prove it, but are you going to take them to court? Are you going to step in front of a judge and say "yes, I violated federal law and removed my DPF, but that didn't cause this failure" and risk a much higher fine than the cost to repair your truck? Doubtful as that would be financial suicide.

I don't know that I would go that far... To reap the full benefits of any exhaust change, sure you need to tune it, but you don't have to. Magnaflow already has systems out that are bolt on and I've talked to MBRP and they expect to release a system in 60-90 days.
I "think" the Magnaflow is leaving the DPF and is installed downstream of the DPF. I could be wrong though.

I thought that removing any of the emission system caused a CEL, therefore needing a tuner to turn it off. And that just removing and replacing the tail pipe would not have any effect on performance, so what be the point of that.

According to the law, the auto manufacturer has to prove that the aftermarket parts causedepartment the failure, otherwise they could say an silly filter causes your power steering to die.
That being said, while unlikely, if your turbo dies after you remove the exhaust system, it's a pretty safe bet Ford will rightfully deny your claim. I will not be deleting anything from my truck, as alimony getting ESP.

Changing just the muffler and leaving everything else the same does ultimately cause the engine to behave different due to air flow out. Ford does have a good case of denying an engine warranty claim and it will be up to you to prove the muffler did not cause whatever to go wrong. Not using a Ford approved air filer could be enough for Ford to deny warranty.
Now, the likely hood of all of this warranty denial happening for a different air filter or muffler is pretty slim. You aren't doing anything major to the engine/drive train. I am still going to do what I want to the truck in the end and if one of these unlikely scenarios comes up, I will deal with it then.

I need to go crawl under my truck and look, but its 5 degrees outside
I thought there was the DPF and then a secondary muffler downstream of the DPF that the Magnaflow was removing. I believe all of the O2 sensors are just upstream of this secondary muffler.
