I'm looking to make the switch from Dodge Ram to a 2013 F150 5.0L. I ideally wasn't looking for a dual exhaust but the truck I like just happens to have one on it. I just wanted some opinion on this exhaust. I don't know anything about it but I have a few pictures of it. The dealer doesn't seem to know much about it either.

My concerns is that it will decrease gas mileage. Obviously it's likely hard to say exactly what it will do by looking at pictures but I'm sure someone can point me in the right direction on what to expect.

Would you consider it a good or bad thing for this truck to come with this exhaust? I am having mixed feelings. I certainly can appreciate a nice sounding exhaust as long as its not real loud. But I also don't know much about them other than reading online that they seem to decrease gas mileage.

Thanks guys!

If it's sized correctly you shouldn't have any problems. If they put one that's too big, it might affect it, but I doubt you'd be able to notice. The real kicker will be if you can keep your foot out of it so you can hear the exhaust. Lol.

Where's the picture?
But good chance it won't hurt you to a noticeable level. Usually it's bc people tend to get on the go pedal a bit more when it sounds good.

Sorry not sure what happened with the photos on the original post.

If the factory could have gotten more MPH by putting true dual exhaust on they would have.

Looks like a Flowmaster. Reports used to say that those caused a loss in low end torque, but I've never seen actual dyno sheets to prove it.

If it's a flowmaster will I lose any mpg?

If the manifold and y-pipe are factory, you won't lose anything (torque/hP/MPG). If you do, it'll be so minimal you won't know it.

Either way, it'll use less gas then the hemi you're used to.

Cat back exhaust on these trucks or any modern truck/car really won't gain/lose anything really except for sound. Usually when people put aftermarket exhaust on they get on it more because they want to hear it. The one issue I see is if you are not used to a louder exhaust or don't like drone, that flowmaster setup without the factory resonator will drone quite significantly at highway speeds, but it also depends on what you can tolerate. Shouldn't be a deal breaker though as a muffler swap is pretty easy and or just adding in a resonator. Flowmasters don't flow as good as other manufacturers or even the stock muffler however what loss there is really isn't going to be noticeable.
