I really wish there were two people in my area with both so I could tell in person.

 

where you live at sleeper?

 

Took the car on the Highway and the American Thunders from 4th to 5th are sooooo loud.....Glad I changed from the Stock mufflers....Or yea at the Light they do rumble a bit and when you take off slow they are really loud.For the price it was well worth it..JohnnyT

 

They are a lot louder under light acceleration at low RPMs.

Sorry I can't compare with the SLPs because I haven't heard them in person, but, I know I wake up my neighbor every morning!

 

I just had someone tell me they were "too loud" today. It was a female but I didn't there was such a thing as "too loud." Under normal driving they are louder than stock but when you floor it, that's when they really wake up.

 

If the people that live next to yea say that the american Thunders are too loud,I would tell them go sue ford.I am sure most would not know if they are stock or notttttt.JohnnyT

 

Los Angeles.

 

I heard an 05 with Flowmasters once, but I don't know if they were the Thunders. Whatever they were, they were not as loud as the Loudmouths (and frankly, I can't imagine any muffler being louder than no muffler. )

 

I want to see relatively how they compare. I understand the LM's will most definetly louder I want to know how loud in comparison to the LM's.

 

Trust me, you will not be dissapointed with the Flowmasters. My parents and my neighbors always know when I'm rolling into my driveway cause its loud. My mom thinks its annoying, but I always get that comment from my dad, "I knew you were coming home cause I could hear you up the friggen street....." LOL

 

I've got the American Thunders and I have driven all summer with the windows down and the AC on just so that I could listen to that deep throaty rumble when I down shift. Yeah, I know it sounds dumb, but it's sweet music to my ears.

 

How's the drone with flowmasters? Minimal? I know there was that article written by Flowmaster stating no drone, but that's the real life experience?

 

There is a little drone under load around 1500-2000 rpm. Its not bad at all...nothing that will rattle your teeth out.

 

Let's compare your Flows to my Hookers this Saturday morning

 

I mean how loud do yea all want?American Thunder is much louder then the Stocks,,,When they are too loud its annoying I am sure.I see Kids with Old Stangs and you hear them a mile away,At least The Thunders Give the Stang a bit more class.JohnnyT

 

I can't speak to how they sound on the '05/06.... but I've never been more impressed with anything other than Flows. That's what I run on my Bronco, and I've ALWAYS loved the way they sound on the '04 and older Mustangs. I never bought them for my Mustangs, 'cause I just took the mufflers out. But, I always wished I had spent the money on the Flowmasters... even running straight pipes didn't sound as throaty... just didn't sound quite as good.
