I have a 2013 F-150 Platinum with a 3.5L Ecoboost engine. I would like to remove the muffler and run dual straight pipes from the cat back and out the rear. Would this create a problem with the computer or engine?
I just put a straight-piped cat-back dual exhaust out the sides last week on my 2013 Platinum. I have had straight-pipes on previous vehicles (V8 Tahoe and Silverado), and the sound on the EB is much different. It is very mellow sounding actually and much quieter than I thought it would be. With the V6, you don't get that low V8 rumble. This is more of a higher pitched hmm. Not sure if that is the best way to explain it or not. It sounds somewhat similar to my Flowmasters on my 2011 Avalanche.
I have been planning on taking a video, but haven't got around to it yet. There are several videos on YouTube if you search for "Ecoboost straight-piped", but don't judge purely on the videos, cuz they do not replicate the sound 100%.
Here are some that I found in my research (pretty sure a couple are members here):
At first I wasn't sure if I liked it or not. But the sound is really growing on me.
