2026 Lariat Ecoboost Rear Drone Noise

[Chops]

Maverick 77 - it seems your underbody heat shielding was not re attached properly looking at the various pic?

That could vibrate at high speed causing a drone?

The exhaust system is not covered by any warranty. Not even the 3/36. It is considered a consumable like an oil filter.

I did not know that. Now I won't feel bad if I replace it with something cooler sounding.

I just looked at my 2026 Lariat, i can confirm the unused hanger seems to be normal. That seems like a lot of rust, unless it's seen time on salted roads I suppose. The date at the bottom of my window sticker says 12 10 25, I didn't think to look at that on the truck itself when I was looking at the exhaust. This is with 600+ miles, with several trips up and down the very muddy road I live on.

What is your opinion of the noise in your 26 Lariat? Does it get loud in the rear?
Your window sticker says 12 10 25 and mine says 12 11 25. The decal in the driver doorway shows 01/26. Quite the coincidence.

If a shield was not reattached properly, it definitely would vibrate. When I had the backend on the ramps today, I grabbed the felt and tin shielding at several places, but I did not feel anything was loose and did not notice any unused hold down spots, but these 66-year-old eyes could have missed something.

It seems to mainly depend on the quality of the road surface. Recently paved roads are super quiet, where some rough sections of road were almost alarming. Sections where I didn't really notice noise in other vehicles, at that. My primary car before this though was a 6.4L Challenger, with the active exhaust defeated. Its tone was pretty dominant over most other sounds. I wouldn't say the Maverick is unacceptable overall, especially with the stereo going and A/C, but it does seem to amplify some road noise conditions.

I still have the Challenger for a short amount of time, I'll have to purposely listen the next time I drive it on the stretch of road most noticeably loud in the Maverick. It is the kind of tone that sounded like grinding differential gears in the Maverick, like I first thought something bad had happened.

I'll have to look on My 2025 and see if mine is the same.

Maybe Mavericks with the heavy GPF will need additional support? Still need to add a new hanger connection to the unibody?

Those without the GPF but have the “phantom” hanger on the pipe only will be “collectible”

You might be onto something they probably just use that same pipe with and without the GPF and maybe the ones with the GPF have the hangar body mount.

Here is a picture taken underneath the Maverick from the driver side looking towards the rear of the truck. The unused hanger mount is circled in yellow. There is nothing above it on the chassis to attach it to. This would not be my sound problem, but there is a large gap between the hanger behind the muffler and all the way to the cat. You would think something has to give eventually with age.

Do both of Your Mavericks have the GPF?

Maverick77, the OP, does not have a GPF. Like me he checked before purchase.

When I cut my exhaust (right about where the mystery hanger is) to install a catback - I was surprised that the long piece of pipe leading to the catalytic converter was unsupported.

Luckily it had a flexible mesh connection at the cat that allowed it to move while I grabbed a box to prop it up. If it was welded it would have been stressed.

Anyway, my aftermarket catback hangs a bit lower than OEM even using the OEM hangers. Another hanger location would would have helped.

I didn't even know what that was until right now, but after searching photos it appears I do not.

My 2024 AWD Ecoboost from Mile one has always been super quiet in the cab at speeds up to 103 mph.

Same here.

Weird! I guess that is one of the few changes between the 25 & 26 model years…

do you have a GPF on you Ecoboost?

No GPF.

I knew they were coming and checked underneath before purchase. Although I think they are a good idea for improving air quality for breathing humans - so I acted a bit self serving in my choice. Did not want the so called extra complexity & maintenance.
