Flowmaster American Thunder muffler for the 2021-2023 Ford Bronco 
I included sound clips and steps to install on my 2022, 2.7 L.

Wow! This video helped a lot in trying to find just something that's upgraded from the factory now. Did you notice any fuel economy change on top of it?

[@UnitedStites]

Hey - hoped it helped. I honestly didn’t notice any change in fuel economy. I did notice a little better fuel economy with the Pedal Commander.

[@RealityMusic912]

Am I crazy or does your twin turbo sound louder than mine?

[@justinfroehlich7019]

Be sure to do a follow up review after a month or so. Thanks.

Thanks for sharing. Does this void warranty for any potential engine issues, something that Ford would use for an excuse?

[@UnitedStites]

Hey thanks - nah, I wouldn’t think this would void any warranty items.

[@devonquinn8750]

Would you recommend it? My concern about Flowmaster is I had an axle-back Outlaw on my Challenger and it droned like crazy on the highway, I don't remember the exact rpm but it was consistent. On that car I eventually went with a full cat-back Corsa Extreme and it gave a nice sound with zero drone, considering the same for my Bronco.

[@UnitedStites]

So far I have been happy with it. You really don’t hear much on the highway and droning would be a deal breaker for me. I have a short highway trip today and can keep you posted.

[@UnitedStites]

Well after about a 2 hour ride on the highway today I wouldn’t say it drones real bad but there is a little hum.

[@khalildagher7055]

I had the Outlaw and that thing was LOUD! I live in an apartment block and when id start it every morning it felt like the entire building was shaking. This honestly sounds like a great option in comparison - Mild but also kinda aggressive. Now that you've had it for a few months how are you liking it?

[@UnitedStites]

I honestly love the sound of this one. I have heard probably 5-7 other exhausts in person on the Bronco and they were too load for what I was trying to accomplish. I live in a neighborhood and my neighbors tell me they still hear it, especially on cold morning startups but overall it is much milder than the others I have heard but has the growl when you get on it.

[@khalildagher7055]

@@UnitedStites Thanks man! Was thinking of the Borla S-Type, but the American Thunder seems like the perfect balance.

[@CrazyKZ777]

What are you saying that that pssst sound is? That would be annoying.

[@UncleFjester]

Annoying AF!
