The 3 Best Axle Back Exhausts for 2015+ Mustang GT 💨

[@Knards]

I have the Roush Axle back hooked up to an X pipe. Yes, it wakes the neighbors In the next state

[@carlosdeleon9593]

I do too. It’s not that loud with stock cats

[@dustinwallace3835]

Try x pipe and muffler delete if you think having mufflers is loud.

[@TheBrettster16]

MrMrwilson11 and I have long tubes and an x pipe and I want to get the roush axle back am I gonna wake up the nation?

[@Dee--Jay]

you get any drone on the highway with this setup?

[@Knards]

@@Dee--Jay Nope. the Roush axlebacks have no drone at all

[@CrackerBDingus]

I have a roush axle back and lethal performance H pipe. When I leave for work at 5:20 in the morning, I'm sure my neighbors are using it as an alarm clock.

[@ademhasanovic7141]

CrackerBRagin Justin asked why at 5:20😜

[@_Anthony___]

I wished I lived near you that's when when I wake up

[@Dee--Jay]

you get any drone on the highway with this setup?

[@CrackerBDingus]

@@Dee--Jay A bit, not a ton. I did a swap to Thermal R&D 2 years ago now, far happier with the tone and volume.

[@thisguyferny242]

Borla should always be in the top three they have great quality, no drone, and the best part is that it's made here in the United States of America!

[@americanmuscle]

What do you think of our top 3?

[@RobertKohut]

Nice choices for the "mild to wild" ranges. Each have their distinctive sound and I think all three may appeal to the masses. My opinion is nothing is great until the resonator is deleted and replaced with an X-pipe, then a muffler choice can be made!

[@l3anzai28]

I woulda done CE, Roush& Kooks

[@BmacRDX]

I don't like the Flowmaster sound at all. The FRPP Touring and Roush are nice choices. The Corsa Touring would make a better mild option, IMO.

[@brentgath4447]

Borla would be my choice, for sure. But they all sound good.

[@Random12231]

That Roush with a quality H-pipe would be magic

[@lvmykdz5724]

I agree, I installed the Roush with an H pipe and I love it. As for the neighbors, I try my best to show respect by feathering the pedal on my way through of any residential areas.

[@Dee--Jay]

you get any drone on the highway with this setup?

[@lvmykdz5724]

@@Dee--Jay No, I don't. If I were to do it again though, I would install Roush only, no H-Pipe, just too loud, especially on cold start.

[@Dee--Jay]

@@lvmykdz5724 i got outlaws but the drone on the highway was just i sane. I had to put the resenator back on.

Nice choices! Liked as always!

[@Stanley112803]

Borla and Roush are my two favorites, regardless of sound tune.

[@GetShrektMrKrabs]

Now all we need is a 2011-2014 5.0 vid

[@noscx]

Ford racing by Borla is awesome, build quality is incredible and great great sound. I can start my car at 5:00 am to go to work then I can beat on it later in the day and it sounds awesome.

[@deejay4839]

I'm an older guy I am the hate you neighbor but I do own a 2017 Mustang premium GT and the stock muffler is not cutting it. I want a head to turn a nod of acknowledgement but not angry scowls. Moderate, noticeable is good for me.

I had mbrp on my 2015. It was amazing

[@sagoatgaming8017]

Which mbrp?

[@Unknown-pl1eu]

My Roush Axel Back arrives this Thursday.. can’t wait!

[@wilhernandez91]

roush axle back and H pipe makes the GT sound like a Beast

[@mathewhastings9485]

Not only did I get my roush axle back kit from American muscle and they fit perfectly on my 2020 mustang gt. I will say that he is telling you the truth about how loud this system is, I had a custom xpipe installed along with my kit, it sounds great and is loud inside and out during acceleration, but it has pretty much zero drone going 80 miles an hour down the highway and the stock actually had more drone at higher speeds. If you are looking to get noticed, then you will definitely do so if you chose the roush axle back kit with an x or h pipe.

[@allthevibes46]

I have the roush paired with a mrt h pipe, sounds lovely. feel bad for the neighbors with the eeeaaarly morning cold starts though hahaha

[@iwanov15]

Same here 😄

[@imds123]

Is it me or does the flowmaster sound almost the same if you went with an H Pipe and kept the factory mufflers?

[@nasserhamood7265]

Roush is best

[@grahamcouture6786]

Here's a suggestion for future exhaust sound clips: include a cold start.

[@americanmuscle]

Noted! Thanks for the suggestion Graham. -Justin

[@grahamcouture6786]

AmericanMuscle.com you're welcome! I really like your videos and they are very good, but I think we can both agree a good cold start sounds great!

[@MustangGuru]

I have a idea I’m working on, I’m taking 2 Cherry bomb bullet mufflers welding a 2" pipe between them to make an H pipe to put in place of the resonator. And removing mufflers out back. What I’m hoping for is a sound like the FOX body or the sn95 sound, that deep hollow sound. Wish me luck.

[@Dude-tb8ry]

Updates?

[@rik1184]

only way to go is cat back . and that borla sport is great.

[@buschg7106]

Flowmaster tone is unbeatable

[@michaelreitz6838]

All good choices. I bought the Flowmaster Outlaw series for my Mustang and am very happy with it. And as you said in the video it's really loud and yes even inside the car at times. But I personally like it that way.

[@americanmuscle]

There's nothing wrong with a loud exhaust :P Glad that you're liking your Outlaw exhaust! Thanks for watching and for sharing Michael. -Elaina

[@Xielent]

I have the outlaws with an h pipe and I wouldn't change a thing about my exhaust setup

[@Dee--Jay]

@@Xielent you get any drone on the highway with this setup?

[@169abr]

Dee Jay yes, all loud flowmasters drone. It’s the price you pay for having a loud and deep tone.

[@hivoltagefx4]

No Corsa Extreme?? How about the Borla ATAK??

[@americanmuscle]

Corsa Extreme doesn't exist in axle back form for the S550. However it is my top choice for the wild 'catback'- be sure to check that video out as well. -Justin

[@lanecornelius9594]

The Corsa Extreme sounds amazing on my '13 5.0!! I went with Kooks long tubes and off road x-pipe to crank it up even more.

[@kentscott9417]

Lane Cornelius exact setup I want to do when I get a muscle car that those parts can be made for

[@MrDatboichamp]

I have the Roushs on mine and I love it! I live in an apartment complex so it’s taking everything in my power to not by the xpipe

[@dwshehanF150]

Love my Roush axle backs with the Roush X pipe, pure symphony!

[@bespinoza66]

[@iTzTJlol]

It’s really loud lol I have the Roush axle backs with a roush h pipe.

[@bespinoza66]

@@iTzTJlol I know lol, I changed the axle back to stock lol

[@CalebWilliams.95]

I feel as the pypes pype bomb should be on the list. They are one of the cheapest options but I feel as they are the best sounding as well. I've gotten plenty of compliments on my 16 GT/CS.

[@jmatson8234]

I have a Roush axle back love the sound 🤣.

[@OFFICIALRover]

How loud is it

[@wiliamsanchez8972]

Justin you should do a video with your top 3 tunes for 2015-2017 mustang gt.

[@robertshanahan6623]

I noticed the Ford Performance mufflers now say "Ford Performance by Borla" instead of "Ford Racing by Borla" in line with Ford's rebranding of the performance division. Do the chrome tips also say "Ford Performance" instead of "Ford Racing", because the Ford Racing logo was so much cooler.

[@buzzcrushtrendkill]

Great information. I was looking for something with a touch more presence than stock, but keeping a deep throaty sound without any fart cannon raspiness and no drone at highway speeds.

[@marksowerby1163]

buzzcrushtrendkill Me too. Have you chosen or upgraded your exhaust. Most options seem too much for me.

[@joseh9021]

Got the roush and man does it sound sexy af!

[@brandonbeals6323]

You guys should do a comparison video for the 2015-2017 F150 5.0l catback exhaust. I can't decide on which catback I want to go with. I know I want something that is extremely aggressive and loud to where my neighbors will hate me in the mornings. I have narrowed it down to 3 options either the Flowmaster Outlaws, Borla ATAKS, or the Corsa Extremes. Help

[@alexchadbourne]

You should do a review on the solo performance street race catback

[@carlosdeleon9593]

Bought a used s550 with Flowmaster 40s (or something like that) and it sounds pretty lame. Gonna have to go with that Roush.

[@xjester1975]

The classifications of axleback volume in this video do no jive with the loudness meter displayed on americanmuscle.com. While not a huge deal, I'm sure that has the potential to cause some level of disconnect/confusion with prospective buyers.

[@6.2_zeus]

What's louder straight pipes with an Xpipe or corsa extremes or roush axel backs with Xpipe?

[@ams914]

How do you think the American Thunder will pair with an h pipe? I want a nice rumble without crazy volume or drone, as I need to be able to do highway miles as well.

[@ryanpanahi217]

Top 3 is awesome. Yall should do top 3 exhaust for all models V6 and GT's. :)

[@americanmuscle]

Glad that you like the Best Of videos Ryan :) We will keep your recommendation in mind! Thanks for watching and for taking the time to comment. -Elaina

[@ldreese33]

I have to save my nickels and get a Roush system on my 2016. Does it drone in the cab on the highway? Does having an automatic make any difference ?

[@nicholaswidlewski8876]

Any chance you guys(and gals) might be doing a review of the Active Exhaust version of the American Thunder kit on the Mustangs in the near future, OR have heard it in-person & have thoughts? Those kits use one-off mufflers that Flowmaster themselves told me are closest to the single-chamber deltas, so they're a bit different from the 44s on the regular kits. I have a 22' GT ordered, to arrive in around 8 weeks. I'm very curious what that kit sounds like(aside from Flowmaster's own videos), but it's freaking impossible to find any reviews on that kit!

[@natepritchett5062]

I have Roush axle back with h-pipe cops got called a couple time because how load it is

[@reconsoundproduction]

can you do a top three exhausts for 04-08 f150s ? maybe make a series for all the generations of mustangs and f150?

[@SavageBodybuilding]

I love my Borla atak but man my top pick would be the Stainless works retro cat back that thing sounds amazing too bad they only sell the cat back for it and not the axle backs for it.

[@americanmuscle]

Have you heard the Stainless Works LMF? That thing sounds insane too! -Justin

[@Stanley112803]

AmericanMuscle.com is that 304 as well?

[@americanmuscle]

Indeed it is! They have it with an H and X pipe as well. -Justin

[@Sanchise32]

What about the new AWE touring axle back?

[@samuraisam6781]

So I guess with that big ass resonator a muffler delete would be just fine?

[@johnbbrose486]

would these options work on the v6 also or are the pipe sizes different?

Is the stock pipe H or X ?

[@pacific7775]

Great video ... im a flowmaster guy , that nostaligic sound coming from a fox body with an off road hpipe is "the mustang sound" and with the 40 series instead of the delta flows it would have made this coyote the top sounding exhaust (my opinion ) but as far as these three go , that roush sounded great.ps my catalogue just arrived cheers.

[@stevenp3176]

Can these be 1 day shipped?

[@dannydinmore]

With the sound test is this just an axle back exhaust or is the resonator been swapped or any mods to the featured cars? Cheers

[@americanmuscle]

Hey Danny- these systems were tested with the stock resonator in place. We wanted to give the most accurate representation of what the axle back would do by itself. Hope this helps sir! -Justin

[@ademhasanovic7141]

Hey Justin, what's the difference between an Axleback with and x pipe/h pipe and a catback?

[@user-bs6ln3ns4u]

Adem Hasanovic h pipes are normally more deep sounding whilst the x pipes are normally raspier

[@Jrv200008]

How loud is the Borla Touring exhaust? Im from the Netherlands and our cops are allergic to loud exhausts so I'm looking for something a little louder than stock but not crazy loud. Would the Borla Touring be a good choice?

[@americanmuscle]

Out of Borla's line of exhausts, the Touring would definitely be your best bet. The Touring systems having a louder than stock tone when you're really getting on it. but when you're cruising on the highway or being light on the pedal it is not obnoxious at all. -Zach

Hey guys just got my rough axle back installed. I noticed I loss some low end torque. Is this normal? I was under the assumption the only thing that would change is sound.

Did you dyno before and after to confirm your suspicion? Because that is highly unlikely for an axle back. -Justin

[@jcrisen5417]

AmericanMuscle.com no I did not dyno it. My gt is brand new with 2000mi on it. Right after I got the exhaust installed I noticed it wasn't torquey at slow speeds and low gears as much before the stock exhaust. It sounds amazing though but just wanted to see if anyone had similar effects with low end torque.
