Not too loud.

This muffler has a great sound. I replaced the factory muffler on my stock single exhaust with this 10 series and some adapter pipes. Love the sound, not too loud or raspy. Very little drone!

will these sound better/louder than my m-80s ?

  • Deeper tone, not necessarily louder. Certainly not quieter either, just different.

Are Flowmaster Super 10 series better than Borla S stingers?

Blaise

  • Flowmaster 10 Series and Borla Stingers are two uniquely different mufflers. The Flowmasters will be very aggressive and have a loud tone. The Borla Stingers will have an aggressive tone that is strictly Borla transformation. Both mufflers are two of the best sounding Mustang mufflers with unique characteristics.

With the flowmasters 10 series does it backfire when you let of the gas?

dfonseca94

  • Back fire is not the correct word for it, but it does have the "popping" effect when it is dropping rpm.

    Aggressive sound

    The best exhaust if you're looking for an aggressive muscle sound. Great sound at idle and open throttle. Interior sound is great without drowning out anything else inside.

    mustang v6 owners

    I have a 2010 mustang 4.0, I have been hunitng for a aggressive sound for my mustang. With price and sound being crucial, i did a lot of studying on muffler sounds on a 4.0. This flowmaster super ten was my answer. It delivers a great rumble with my dual X pipe and it growls on the roads and highway. The flow also moves much more efficient out the tail pipe and I did feel a slight difference in power with these mufflers compared to my old ones. the moment you start it up it sounds aggressive. I have seen more heads turn with these mufflers than my old ones. It is worth it for a V6.

    great sound!

    I have a MAC prochamber off-road mid pipe. It was paired with slp loudmouth 1 catback set up. WIth no cats the slp was too raspy. So I installed flowmater 10s and it is just as loud like I wanted but it is deeper and it sounds more like a mustang was meant to sound. Overall my 04 GT sounds like a beast now and I love the sound.

    Simply Amazing

    Even though I have a v6 as a new father I have to make do on what I have. So the First thing was to change out the exhaust. Got rid of the Y pipe and had a custom H pip installed. As for a stock setup I wanted the flowmaster 10s to do their magic. Flowmasters were the way to go. Nice deep rumble and screams at WOT. Driving under bridges and tunnels are heavan. This was a good purchase. Setup Stock cats, H pipe, Flowmaster 10s

    must have for your mustang (GT)

    This is awesome.......super 10s is a must have a deep loud roar that you expect from a muscle car i have them on my 2000 gt sounds like a cobra, recommend to keep the cats on or your a cop magnet but with stock exhaust set up sounds nice and aggressive will turn alot of heads promise!

    Just do it.

    Wow. I just recently bought my mustang and it had some bullet style mufflers on it that sounded good, but i had no idea what they were so I wanted to get a good muffler that sounded good and was some what cheap. These honestly are not as loud as everyone makes them out to be, don't get me wrong the super 10s are not quite by any means, they have a fantastic american muscle sound to them and i am very pleased with my purchase. So if you are scared these will be to loud don't worry, they are the perfect mix of loudness and tone. Off road H or X coming soon and i can't wait to here it then! Thanks AM!

    AMAZING EXHAUST SOUND

    A very mellow aggressive deeper exhaust note unlike the 40 series I had before, got to love that almost V8 throaty rumble sound coming from my V6, the compact design give you a lot bang for your buck.

    awesome

    i had these on before american muscle carried them on their web site. they are an awesome product. the loudest of the flowmaster series. they add a deep deep rumble with the resonator rasp and crackle its the best of both worlds. i have them paired with a BBK o/r x-pipe very satisfied.
