New! Flowmaster FlowFX Series Straight-Through Performance Mufflers

[@redlinered_rt6174]

Just got these installed on my 2015 Challenger R/T and they sound awesome! Very aggressive but not over the top... exactly what I was looking for... and I shaved a tenth off my 0-60 right away! I highly recommend these for anyone looking to make their Hemi sound like it should have from the factory!

[@FlowmasterInc]

We're happy to hear that you love your new Flowmaster FlowFX mufflers. Did you have them mounted in the center location or in the rear of the vehicle? Any sound clips yet? Thanks for your support! - Jason @ Flowmaster

[@redlinered_rt6174]

Correction: I shaved 3 tenths off my 0-60. Ran a 4.7 today. Prior to the muffler install the best I could get was a 5.0. Do these things help performance? Very much so in my opinion! The numbers don't lie! I had them installed in the center where the stock mufflers were and had the rear resonators removed. I'll post a clip of a cold start soon 😁 Thanks!

[@FlowmasterInc]

Can't wait to see that vid! 🤘 - Jason @ Flowmaster

[@redlinered_rt6174]

Just uploaded a cold start video 👍😁

[@FlowmasterInc]

And it was sweet!

[@gd1996]

Just installed a pair on a 06 magnum rt 5.7 hemi, good rumble, noticeable exhaust tone, but not too loud that you'll have mad neighbors. Very well made also. Wish they were a touch louder though. Hard to beat for the price!

[@jerrodabbott1425]

I bought the round flowmaster fx and i love it is a perfect muffler sounds amazing put it on a 97 mercury grand marquis 4.6 removed the cats true dual exhaust simpley sounds amazing i love the price of these mufflers and are made awesome to i am very picky when it comes to mufflers i will be putting them on my mustang and my dakota rt thank you flowmaster for these mufflers they are simply amazing

[@AlastorTheNPDemon]

Seems like an excellent product! Unfortunately, I did the dumb thing and ordered a diameter pipe that my muffler shop couldn't work with, so I got louder Super 44 muffs instead. No regrets; I rather like the bassy, earth-shaking drone of the 44s. It's cool, because the exhaust note changes personality drastically with exhaust system temperature and engine speed; sometimes it's an imposing howl, sometimes a complex rumble, sometimes even quiet. Very interesting.

[@98boss1]

Have the FlowFX muffler on my 2019 ram 5.7, gives a nice tone at idle and under throttle without being overly Loud. Only downside when the 4 cylinder ECO mode kicks in it does have quite a bit of drone

[@alandelgado798]

Had mine for about 2 months, in place of a super 10 & it sounds great, I love it! Exactly what I was looking for!

[@FlowmasterInc]

NICE! - Jason @ Flowmaster

[@silence3314]

Is it better than the 10? I have the 10 now

[@FlowmasterInc]

The FlowFX will be more moderate than the Super 10, yet is still a semi-aggressive sounding muffler option. The design of the FlowFX allows for an aggressive exhaust note with less interior resonance than a conventional chambered muffler. I can't say that it's better, it all depends on what type of exhaust note that you're looking for. You can always give us a ring at 707-544-4761 to see if the FlowFX will make a good addition to your ride. - Jason @ Flowmaster

[@alandelgado798]

Not to say the super 10 is not a great product, it is & still love the sound but the flow fx is just what I was looking for. Interior & exterior sound, can't beat the price either😊

[@smww503]

Just installed this catback with dual side exit on my 2020 f150.sounds good at normal driving but gets aggressive when you get on it

[@EsotericFleetMechanic]

Sound awesome on my Subaru with UEL headers and high flow cat!

[@808G8GT]

REBRANDED MAGNAFLOW MUFFLERS. Look at the case design, welds, packing, etc. The best sounding FM in opinion is the Hushpower II shorty mufflers. Best of ALL worlds. DEEP, Powerful, nonraspy, non-tincan, sound.

[@RoGuExPaNcAkE]

These are nice but my favorite is still the super 40 and 44 guys. But this is really nice option

[@vgcringe9996]

Would have been nice to hear it with a cammed idle.

[@HarryPNess-ly7qp]

@flowmaster Any drone with these if resonators deleted and installed in the end of the vehicle

[@jasonneal]

The cars they demonstrated sounded like stock exhaust. Idk, I’ll stick to the original 40’s and the super 40.

[@jamesfarabaugh6669]

Would be nice to hear on an old carbureted pushrod V8. How would it compare to a short (about 20") cherry bomb glasspack?

[@FlowmasterInc]

While unfamiliar with that particular "straight-through" design the tone on these sounds awesome on a number of vehicles and applications. - Jason @ Flowmaster

[@tobydoucette8529]

Just ordered one for my 05 tacoma 4.0!!

[@tobydoucette8529]

And it sounds nice and deep love it!

[@kevinbennett3244]

@@FlowmasterInc they dont make one that has DI/DO?

[@FlowmasterInc]

Kevin Bennett Not yet, it's currently in the works. I have been waiting for a DI/DO option for a few months now. Hopefully, we'll see a dual in/dual out Flowmaster FlowFX before years end. Next month we'll be introducing a cylinder style FlowFX muffler that may work for your application. More details to come on that new option, we should have info available on our website www.flowmastermufflers.com after the first of October. - Jason @ Flowmaster

I'm about to post a video soon I just got 2 round 3 inch they are going on a Colorado with a cammed 5.3 tri-y headers straight into the mufflers no x pipe we will see how it sounds I will post a video soon

Getting two for my 85 c10 with a 5.0

[@EfurdGarage]

I think I'm going to try some on my v8 s10

[@vmiley1]

I already have your Scavenger Series Resonator Delete Y-pipe on my 2018 EcoBoost Mustang, & want to get your FlowFX Axle backs #717789. Looking for a deeper tone, than stock mufflers, without all the popping most mufflers produce.

[@insulator1one]

I'm looking for a quiet exhaust for my truck. I guess something slightly louder than factory. Would you say this exhaust is a lot louder than a factory exhaust? I have a 90s 5.7L Chevy truck

[@FlowmasterInc]

The Flowmaster FlowFX muffler is considered a moderately aggressive muffler and will be very noticeable over the stock one. If you're looking for a muffler that will give you a mild exhaust note then the 70 Series or the 50 Series Big Block would be the way to go. If you need additional options please give us a call at 707-544-4761 and our Support Team will help. - Jason @ Flowmaster

[@sdotcam1]

Ordered my set yesterday!

[@FlowmasterInc]

NICE! We hope that you like 'em! - Jason @ Flowmaster

[@sdotcam1]

Flowmaster Inc just got them installed today. About how long do they take to break in

[@DjDubStak]

I have the 70 series on my Jeep stroker. How does this compare in regards to note and drone?

[@FlowmasterInc]

The Flowmaster 70 Series is one of our tamest muffler options and the new Flowmaster FlowFX is considered a moderate to aggressive option so the comparison across the board will be "night & day". The FlowFX will be more aggressive in its exhaust note and tone and will be more noticeable within the cabin. The FlowFX should sound pretty badass on that setup. If you have further questions about the FlowFX or any of our intake, exhaust or tuner products just give us a call at 707-544-4761. - Jason @ Flowmaster

[@payloadperformance9706]

these sound a little too ricey for me kind of tight and loud sound. I prefer a deep rumble not so throaty I get from the 40 series muffler.

[@SedatedByLife]

I'll stick with my 40 series. Too quiet. Also, wth is with the basic fiberglass pack? Why not the ceramic stuff you use in other mufflers? It's just going to get louder as time goes on

[@FlowmasterInc]

The internal wrap found in the Super HP2, Pro Series & dBX Series of mufflers is a high-temperature internal wrap within the casing that was designed solely to help keep heat within the muffler, good for applications where heat can easily be transferred to the floor pan. The tone of these styles of mufflers is due to our Laminar Flow technology which is two perforated, opposing cones that produce the tone. The materials in these muffler options do not affect exhaust note or tone. - Jason @ Flowmaster

[@MrMustang1973]

Can you install the cat-back kit keeping the factory resonator?

[@FlowmasterInc]

The majority of our Cat-back Systems will delete the factory resonator from the system. On some of our tamer Cat-back options, we include a Flowmaster resonator within the system components. It all depends on what application that you are asking about. If you can get me some additional details on which vehicle or Cat-back system that you're inquiring about I can get you some answers. - Jason @ Flowmaster

[@MrMustang1973]

2017 Ford F150 Super Crew 5.0 V8

[@FlowmasterInc]

We currently offer one Cat-back for the 2017 F-150 5.0L, the FlowFX Cat-back, side exit exhaust, part #717785. This system will connect to the head pipe/Y-pipe and will delete the factory resonator from the system. You can add a resonator into the system fairly easily with the help of an exhaust professional but you will have to modify the Flowmaster system. You can find additional information about this and our other exhaust, intake and tuning solutions at www.flowmastermufflers.com. - Jason @ Flowmaster

So after all these years of blowmasters on junkstangs and General trucks they decide Magnaflow has had it right all along. I'll stick with Magnaflow.

[@bethmann24]

How would this series sound on a Scion tC?

[@FlowmasterInc]

Although we have not tested that combo together I can tell you that when I owned my tC (2013 8.0 Release Series #1237, my favorite car that I've owned) I would have put a FlowFX muffler on it over the TRD muffler that the 8.0 R.S. came with. The straight-through design of this muffler and the 2.4L, 4 cylinder engine should sound pretty badass! - Jason @ Flowmaster

I just got my muffler and after looking into it further I'm hoping the muffler shop can work some magic, I have no idea how it's gonna fit on the car! I ordered the offset inlet and offset outlet.

[@FlowmasterInc]

If that configuration does not fit, take a look at our newest Flowmaster FlowFX muffler, part #71416. This is a tubular style muffler that may fit better in the rear or underneath. - Jason @ Flowmaster

[@hemirt4096]

Would it make your car louder than the 10's???

No, The FlowFX is considered a moderately aggressive muffler with minimal interior resonance (drone). The Super 10 is our most aggressive street muffler offering. If you're looking for the right muffler replacement for your ride please give us a call at 707-544-4761. - Jason @ Flowmaster

[@ClementeGalloJr]

So basically this is a Magnaflow by Flowmaster. I'll stick with the chambered sound.

[@FlowmasterInc]

We listen closely to what our clients want and what the market demands. As much as we love the chambered muffler sound we wanted to design a traditional straight-through style of muffler. On some smaller displacement engines, an aggressive chambered muffler can produce an unfavorable sound and the new Flowmaster FlowFX sounds great on many of those applications. We're still advancing the design of our chambered mufflers and will never forget about our friends that love that original Flowmaster sound. - Jason @ Flowmaster
