This discussion of loud exhaust on nothing but a V-8 is nothing new. The feelings were the same even when I was in high school back in the 1970's.🖖
They date back to 1932 with the first Ford V8

People make this mistake all of the time. They confuse a cool car with a good exhaust sound. I'd bet $100 if I took a sound clip of a cool carb'd old inline 4 and played it over the top of a F&F Honda Civic, everyone would complain about how horrible the exhaust sounds.

People think old cars sound good because they like old cars. Sorry, I4s and V6s have always sounded like garbage and the only thing to do is to keep them quiet.

The other thing I see is "I had an [XXX] with an exhaust and it sounded great!" Yes, and every parent believes their child is a beautiful perfect heavenly specimen. Sorry, your kid is an annoying shit and so is the loud exhaust on your V6 Mustang. It was never good, but you couldn't see that because it was yours and you were blind to how awful it was for everyone else.
Hahahaha so true. I think the real issue is that people equate “loud” to “good.”

I had a decent flow master on my V6 camaro. It wasn’t overly loud, it was slightly more than stock but it changed the tone to be more pleasing at low idle and acceleration. The only engine that should be loud is a V8, dems the facts.

Fwiw, the 3.5EB in my Flex sounds a lot better than a 3.5EB on an Expedition.

Underwhelming exhaust on a Ranger may not be duplicated on the Bronco.

I'm not one of the V8 is the only good exhaust sounds guys all the time. Yes, i prefer it, but ive heard good exhaust sounds from many cylinder counts, but the the 2.7 is not good. I may go the route of trying to hear more turbo instead, as that is a more pleasing sound on this motor than the exhaust imo. At least im not getting the additional sound deadening in the body since i have the BD, so there will be no hood blanket from the factory.

Exhausts can sound good when it is tuned to the specific vehicle from the factory or by the exhaust manufacturer or by use of helmholtz. Unfortunately, most people believe the louder the better. This is why there is such a negative view of anything but V8’s. Because people cannot accept that a 4-6 cylinder isn’t as loud as a V8, they have to achieve the loudness! Listen to my Civic pop and burble and sound like a giant flatulent turd like lawn mower only 100X louder.

Oh yeah. Volume has nothing to do with quality of sound at all. Unfortunately, many people think just uncorking some small motor and making it super loud is a good sound. Not so much.

Nope lol. I go race frequently and when they come up, dear god, they sound so awful. Everyone just looks away in disgust 🤣 They’re 10X louder than 98% of the V8’s to boot. I usually laugh at all the tuners that sound like they’re going 180MPH but they’re driving 18.

Here’s what I wish our Broncos sounded like (old school V8 power). BTW this is me driving my 63 Split window, 327, 340hp, solid lifter. Listen to it with air pods for maximum effect. It sounds mean without sounding obnoxious. This is what it sounds like inside the car. Outside it is a musical symphony 😃

I have one neighbor that wouldn't agree with you and over a dozen other neighbors that definitely would agree with you (including myself.).

Here’s my 63 on a lift at idle and a couple of revs. This is the sound I would love in my Bronco.

My 5.3L Silverado w Spintech 6000 mufflers was a beast... also served as an alarm system one night when my wife (now ex) woke me up saying, “I think someone just took your truck!”

Took OnStar a long ass while to shut it down, but better that than waking up and wondering where the hell my truck went.
I imagine spintech on these EB engines will be teh suck. As much as I love exhaust note... will probably try and keep the sound well-hidden on a Bronco.

I worked at a Jeep dealership many years ago. The reason I liked the V8 Grand Cherokees better than the 6-cylinder wasn't just power, but the sound - because the V8's were quieter than the 6's. Even at idle, the 6's sounded like a sewing machine compared to the low-purr of the V8's. (And we won't even discuss revving.) I would have paid for the V8 just for the quieter, less-intrusive sound of the bigger powerplant - whether at idle or driving.

A little loud but I'd be good with the new one sounding like this. It makes me want to do a 347 stoker kit on my '75.
