Differences of the Outlaw, American Thunder, and Force II Exhaust Systems? Please Subscribe to our TH-cam channel: / flowmaster
Flowmaster offers a wide variety of exhaust systems for most popular vehicle applications that produce that deep, legendary Flowmaster sound in mild, moderate, aggressive, and very aggressive tones. Flowmaster exhaust systems are widely available in Cat-back and Axle-back configurations and aluminized or stainless steel construction. In this video, Steve installs and compares three of our most popular series of Cat-back exhaust systems: Outlaw, American Thunder, and Force II and then tests them out on a 2015 GMC Sierra 1500 equipped with a 5.3L V8 so that you can see and hear the differences in design and sound.

I just installed the flowmaster 40 series American thunder. Ome of the best decisions of my life. Terrific volume and amazing sound. Love it. Great job flowmaster!

[@jevonshepherd9214]

Am I the only one that noticed that they drove each one differently which has effect on the sound!?

[@cliffwilson8918]

good day to all an thanks for making a damm good muffler the outlaw rules the streets thats music to my ears am a retired truck driver of 31 years so i know engine noise cab noise and truck stop traffic turbos is the loudest noise under a hood flowmaster is the only product i will but on my bowties be safe on the roads

[@timwickersham869]

I have the outlaw on my 5.2 liter jeep,,,it is frgn awesome!!..the drone is not bad at all,,,but don't think my neighbors feel the same way..lmao!!🤘

[@alexbrock3930]

Excellent video, great job that really broke it down, I think I want the American Thunder

[@dannyboy1794]

Force II test drive for interior noise was ran at 3500 rpms while the other tests were well over 5000. Bummer because I'm interested but not 100% sure yet.

[@N-Scale]

This was a very well done video and thanks for the time it took. A very nice comparison of the systems.

I got the American thunder and custom welded a super 50 onto it, best look and sound in my opinion!

[@dextermorgan9703]

Ive got a super 10 im happy with it

[@ReidHenderson]

I'll admit I'm not a fan of flowmaster for there price. But that is a beautifully built exhaust. Smooth non crushed bends or wrinkle bends. Looks awesome!

[@82raptor]

I bought the American thunder with the super 40 and it was too loud for my taste. I custom welded a super 50 to the American thunder dual system and it sounds AWESOME!!

[@ElmoWV304]

That outlaw series has my eye. But I had my 2014 RAM 2500 with 6.4 hemi converted to true duels. Do you offer a one in and one out for my truck and true duels. 3" all the way back.

[@lanewarriorillridez3739]

Hi Flowmaster, whats the difference between the Original 40 series and the Super 40 serires?

[@timkeough4328]

All 3 sound good

[@jakebrake6144]

That one labeled outlaw looks like a 10 series to me. Idk.

[@jrchevy2500]

American thunder it is. Thanks!

[@robertaguilar6983]

I have a 2002 DODGE DURANGO... would all of your mufflers fit or am I limited on certain ones?

[@FlowmasterInc]

We offer over 15 universal replacement mufflers and those mufflers are available in a number of inlet/outlet diameters, inlet/outlet configurations so there is a good chance that we have the right muffler for your ride. Of those 15 mufflers, we offer a number of different exhaust tone and volume options. If you want loud we got it! If you want tame, we've got it! Just give us a call at 707-544-4761 and our Support Team will give you options and prices.

[@injunboy89]

slapped an American thunder on my 15 ram 2500 6.4, al dente👌

[@joanngordon6473]

That RS1 Exhaust you guys did for my work was sweet

[@domimiquemornes4666]

I’m digging the force 2

[@javierbarbosa4474]

What would you suggest @Flowmaster Inc for a V6 in these 3 set ups you just showed here???

[@FlowmasterInc]

Any recommendation will be based on what type of vehicle you have and what type of sound are you looking for? An Outlaw Cat-back system on a V6 Toyota Tacoma will sound much different than on a V6 Chevy/GMC. My recommendation is to give our Support Team a call at 707-544-4761 and let them know what vehicle you have and what you're looking for from your next exhaust.

[@jjmccloud]

I prefer the super 44s and super 10s with a true dual exhaust on my truck. That's just me but nothing like a built up & cammed 400hp gen1 sbc 355 with dual flowmaster mufflers and high flow cats coming from some long tube headers down 2.5" pipes man that really gets my heart beating everytime I fire mine up and get behind the wheel, especially being a little ole S10 truck. Best toy I ever owned haha

[@MartinFuentes126]

Unrelated question about the mufflers but y are the Flowmaster high air flow intakes not CARB compliant for California?

[@FlowmasterInc]

The process to get a CARB EO# issued is a long process and bit of a costly process. I can assure you that we are making every attempt to get all of our emissions-related components the CARB EO# that is necessary to sell and install on California pollution controlled vehicles. Please check wwwflowmastermufflers.com frequently because we do update our products regularly as new information becomes available.

[@MartinFuentes126]

Flowmaster Inc thank u Jason, if the intakes were CARB legal I would without a doubt purchase the kit. I am Flowmaster faithful, love your mufflers!👍

[@FlowmasterInc]

We finally have some of our Delta Force Performance Air Intakes with CARB EO # issued. September 1st we will be bringing four CARB EO # issued intakes for the Ford F-150 and the Ford Focus ST to market. If you do not see your vehicle listed please be patient we should have more to follow.

[@MartinFuentes126]

Flowmaster Inc that's good to hear. I have a 2003 GMC Sierra so I'll be patient for the manufacturer for the era of my vehicle.
