Straight pipes / muffler delete (question)

[Eco15]

I apologize for asking what might be a noob question, though I did attempt to search for this topic (and am a daily forum reader) but did not come up with much other than chambered mufflers might cause too much back pressure.

I was curious if doing a muffler delete and running straight pipes out would cause any issues with back pressure (or lack thereof rather) with the turbo. I grew up around muscle cars and know that it was common to see this on those, but was unsure how it would change performance with a turbo engine.

I understand that the sound might not be amazing, but so far nothing I've seen has caused me to fall in love with it. I figured I might give this a shot, see what it sounds like in person. Worst case scenario, I'm out a bit of money but can change back to factory without the money hit an aftermarket would cause me. Just hoping to play around a bit and see what sounds like what, but did not know what this might do for performance. I did see the reddit post where this had been done and spoke to the gentleman on reddit, seems worth a shot (for me).

Thanks! :cheers:

The only real danger from running a straight pipe on a turbo is that it might overboost (IE the wheel forcing more air than the fuel system can withstand) I ran a muffler delete on my Focus ST with just the cat and a small resonator and there was no issue. I do know the Mustang is fairly loud when uncorked and will not make a good noise. Personally I would delete the briefcase resonator and mufflers and add two smaller resonators just to keep the sound under control.

I am probably going to do just a res delete to see what it sounds like on Monday. Any thoughts on this as well?

Itll give the car a more harsh exhaust note and help flow a bit. You will notice more popping on the overrun.
