Flowmaster Super 40 Series Muffler Sound Test

[PRIMOCITY]

I just put these on my 1975 Buick regal . Sounds good but I was use to my cherry bombs

[RenwedMinds]

Hi im looking for a good muffler for my 1996 lincoln town car. I want something thats not going to be too loud but still sound pretty good. What would you suggest??

[bravesfan1893]

Which would be better to put on a 2003 Jeep Grand Cherokee Limited V8

[SpeedwayMotorsInc]

@bravesfan1893 In terms of exterior sound levels, the Super 44 will be the loudest, while the Super 40 will be the quietest of the three. Please note that the 40 Series family of mufflers may be too loud for some daily drivers, but this is based on personal preference. If you are concerned about ground clearance, the Super 40 will be the largest dimensionally at 5" thick while the Original 40 and Super 44 both share a 4" thickness.

[bravesfan1893]

@SpeedwayMotorsInc Yea i did some research on them...I think im going to go with the super 44 series...it sounds so bad ass

[SpeedwayMotorsInc]

@bravesfan1893 And all three styles will produce very similar horsepower gains. Please visit Flowmaster’s website and YouTube channel for more sound clips and information.

just had the Super 40 installed on my 2012 1500 hemi. sounds bad ass.

I just installed 10 series on my Cammed out '05 GT. AWESOME SOUND. Feels like I gained a smidge off the line compared to my American Thunder series. The only downfall is the bassy drone on the highway. You think some sound deadening method in the trunk could help elleviate some of the noise?

[SpeedwayMotorsInc]

@TekMan05 Installing additional sound dampening in your Mustang is not going to help the problem. If the drone of the 10 Series is too unbearable, then you need to go back to the quieter mufflers. Adding any additional weight to your vehicle (ex. sound dampening) is going to offset any positive horsepower gains from the 10 Series muffler, which will take you right back to where you started.

[TekMan05]

@SpeedwayMotorsInc Interesting. Hopefully I'll adjust to it. I already am used to some drone. I have a 5.0 Explorer with the Super 40 series. It also has a slight amount of drone. There was a period I was driving with the mufflers disconnected right after the H-pipe. That was loud but had no tone to it. This sounds like the American Thunder series I had previously after it goes through puberty. And it really does seem like there is a small power gain with the 10 series

I have a magnaflow muffler right now and I want to upgrade to flowmaster, I want a nice deep sound at idle and good sound when opened up. The truck is a 96 sierra. What would you recommend?

[SpeedwayMotorsInc]

@KyleParkin0 Without knowing more about your pickup and driving style, it is difficult to recommend one specific muffler. The Flowmaster 40 Series mufflers may be too loud for a daily driver, especially if you are used to Magnaflows. If you are looking for a milder sound, we suggest either the 50 Series (moderate volume) or 70 Series (mild-stock volume) for a daily driver. Please see Flowmaster's website for more information and sound clips.

[KyleParkin0]

@SpeedwayMotorsInc I like to floor the gas every now and then. I want something loud and deep, that gives off a good rumble and a good sound at idle. The magnaflow is to quiet for me.

[SpeedwayMotorsInc]

@KyleParkin0 If you're looking for a sound that will really turn some heads, the Flowmaster Super 44 Series is the muffler for you. It is the most aggressive sounding Flowmaster muffler we sell. We have the Super 44 available in 2-1/4", 2-1/2" and 3" sizes with centered or offset outlets. Check it out on our website!

[KyleParkin0]

@SpeedwayMotorsInc Thanks! which out of those would be the best? 3" center? Dont want something that will be like a straight pipe loud...

[SpeedwayMotorsInc]

@KyleParkin0 The size and inlet/outlet combination you use is completely up to you but feel free to call our Tech Line at 800.979.0122 if you need further assistance.

[KyleParkin0]

@SpeedwayMotorsInc thank you :)

[J30A1TypeR]

Look it up bitch. I said a V6 Accord not a fukin Civic.

[ultrared27]

08 Impalla SS. Hushpower shorties or 44's? (Just mufflers) Can't decide on sounds.

[pedsay]

is the sound different with each individual Engine? I have a small 3.0 V6 Vulcan...

[SpeedwayMotorsInc]

@pedsay Yes, each individual engine will have its own unique exhaust note. The differences in tone and volume will vary with the series of muffler you use.

[dirtbikes72]

@SpeedwayMotorsInc Ok, so the super 44 is louder than the super 10 series? and is the 44 a full exhaust system? or just the muffler at this point with the internet not being my friend, i am getting very confused lol

[SpeedwayMotorsInc]

@dirtbikes72 The Super 10 Series (which we currently do not sell) is louder than the Super 44 muffler. The Super 44 is a muffler only. If you are interested in a complete exhaust system for your Camaro, our part # 378-17201 includes mandrel bent 3" tubing, the Super 40 mufflers and all hardware necessary for a bolt-in installation.

[dirtbikes72]

@SpeedwayMotorsInc OK thank you for your time and help

[dirtbikes72]

@SpeedwayMotorsInc Im looking to put an exhaust system on my 1969 camaro, i have chosen flowmaster to be the exhaust but i have no idea what series to put on it could you please help me?

[SpeedwayMotorsInc]

@dirtbikes72 We generally recommend the Original 40 Series, Super 40 Series, or the Super 44 Series for V8 muscle cars. In terms of exterior sound levels, the Super 44 will be the loudest, while the Super 40 will be the most quiet of the three. If you are concerned about ground clearance, the Super 40 will be the largest dimensionally at 5" thick while the Original 40 and Super 44 both share a 4" thickness. All three styles will produce very similar horsepower gains.

[kc03300]

the mufflers fall apart af a year or so. low quality.

[madtownmadman]

@kc03300 The hell they do. You likely got one of those Made in China knockoffs.

[J30A1TypeR]

Wow. It sounds better on a Honda accord V6

[ultrared27]

@J30A1TypeR Yeah, and I can make that noise with my tounge between my lips too... How do you spell the sound of a wet fart in a can?

[MEXICANMADESTWR]

DO FLOWMASTERS INCREASE HORSE POWER?

[SpeedwayMotorsInc]

@MEXICANMADESTWR Yes, they do. Performance gains vary, depending on your application. The more power the vehicle makes, the bigger the gains will be. Generally in full size vehicle applications, a 5-7% gain of power is fairly typical, while 1-2 mpg can be achieved.
