2015-2017 Mustang GT Roush Axle-Back Exhaust Installation

[@bradvanhorn4613]

Had mine on for 3 days now, and this is what a 435 hp engine should sound like.Coasting down hills is great sound, accelerating is pure joy, and I dont know how much HP this exhaust added, but I can sure feel it. Love those pipes

[@bradvanhorn4613]

Not a drop of drone. Sounds good at highway speeds and lower rpm

[@bradvanhorn4613]

I wouldn't go past the police station in sport mode though!

[@infinitesply7633]

Let me know if you figure out the hp

[@jackhunter8303]

Typical Kickz it’s probably about 2 to 5 percent hp

[@SwishaSilva]

Never realized how quiet the stock exhaust was

[@mikeymk3]

My dad and I used this video while we put my mom's on her car. She loves it and it fits perfectly! Thanks a ton!

[@smithnyiu]

Just installed this exhaust on my 2017 GT. It sounds amazing. Would not have attempted it without watching this video. You gave me confidence that even an idiot like me can do it, and it went just like the video. Thank so much for the great video. Now to go play ...

[@shanefowler9443]

Same bro

[@asingh4136]

Hey did you use a jack to lift your car ?

[@Knards]

These pipes are the best. Wonderful sound OTT, great sound coasting down hills, no drone at all. I do not suggest driving past the police station in sport mode though. Love this exhaust

[@collin3089]

Just helped my buddy install this to his 2015 Mustang GT. Using a proper saw it was easy. We were taking our time and it probably took no more than an hour. Sounds fantastic. Make sure you tighten those clamps down real good. Wouldn't want to loose a can going down the road!

[@DefiantAero]

Excellent video. Thanks for the proper before/after shots and the coherent, detailed explanation. Hard to find on KZbin, even posted by pro shops! Definitely helps me make up my mind.

[@Zerogivengarage]

+lonestarreview Thank you for the compliment

[@cruhcifix7228]

Ive lost track with you guys reviewing so many exhaust systems. Haha great job Bill!

[@Zerogivengarage]

Me too :) I forget which car I installed which system on and guess what I am installing today lol

[@TV1Peter]

Thank you for showing the performance on a highway! With a steady speed I do not want aggressive and very noisy pipe.

[@aidank2]

Thanks for the Video You Guys always do a Super Job.I have my Roush Axle Back but sadly here in the UK we are on a 10-12 month delivery but have you video and next summertime the car is Due and will be installing the Axle Back which is such a Great quality Product as are all Roush Parts and CJ Pony is on subscription :-) all the best from the UK

[@MisterJ.J.]

We have the roush axle back exhaust system on our 2717 GT 401a package with manual stick shift. It sounds very good. It's only loud at cold start up and when revved aggressively. We have enjoyed it for 5 years. When new we had the exhaust tips sent out to be custom powder coated gloss black. Still looks very good. Nowadays you can get the optional black painted exhaust tips from Roush. Next we will be installing the Roush resonator delete h-pipe. Then it will be very loud.

[@MustangsandMavericks]

Rough estimate when these will be in stock???

[@cjponyparts]

Late January 2015.

[@Mykola___]

amazing sound!

[@spacethunder2411]

Put an x pipe in place of the resonator with these mufflers and it will sound even better. You may start to here drone inside the car then though.

[@bninagra8652]

That’s amazing and easy to install

[@akrs6398]

It pops!wow.do you need a tune after this install?

[@cjponyparts]

No tune needed.

[@OldSchoolDisco_channel]

nice sound!

[@hanstah9501]

hey bill! can you guys ship this to the philippines? how long will it take? a reply would be highly appreciated!

[@Zerogivengarage]

We do ship to the Philippines. I can't give you exact time but 10-14 days is probably an average

[@hanstah9501]

SWEET. thanks bill!! you're the best!

[@mcoop6620]

Love all your videos, very informative. Quick question though; On your website, it's mentioned that there will in fact be a quad tipped Roush axle-back exhaust coming soon. Do you know when that might be available, and also, do you think you'd be doing a video on that system as well? I think a lot of people might be interested in an offering like that due to the unique, aggressive, personalized appearance it would bring to the car.

[@Zerogivengarage]

Roush has not given us a release date yet on their quad tip system but we will be doing a video in the very near future on the Magnaflow quad tips.

[@mcoop6620]

Bill Tumas Awesome, thank's for the reply, looking forward to more videos!

[@josepharellano5073]

Is your GT aftermarket ?

[@alliejay9462]

bill please tell me whats louder borla s type or roush axle back for the 2015 gt

[@Mik3yDatBoi]

Roush.

[@joshua7010]

+MikeTheNoob Ford Racing Catback Exhaust :)

[@chrishaugh1655]

Catback will almost always be louder than an axel-back setup, don't be a turd...

[@theways1234]

CJ Pony Parts Were there any mods besides the axle back on the last GT with the white rims? It looked like it was putting down noticeably more power than the first one.

[@roderickstewart4043]

What does the inlet measure on the tips?

[@ochafic3631]

Can you put the installation video / sound of the roush axle back for the v6 2015 !

[@viimezo5327]

Whats better? Putting a whole exhaust system or cutting the end of it and adjusting it like what you did?

[@Zerogivengarage]

A cat back system saves more weight and gets rid of the restrictive resonator so there will be a performance advantage to a cat back. The Roush is a great alternative simply to improve sound.

[@norrisautorepair6250]

My car already had these Mufflers installed they seem to hang a little low same with the tips they're not really snug to the rear bumper it's a base model it shouldn't matter imma check my exhaust pipes see about where they were cut at maybe they were cut too much or too little?

[@undefeated2012]

Which would you recommend, this or the ford racing cat back exhaust?

[@h80282]

roush is the best exhust ever for a mustang

[@MetalGearHead]

h80282 fuck ya it is!!

[@ckrehmeier]

I have this paired with a res-delete x pipe. Will the flowmaster outlaw axleback be louder? Possibly a tonality change?

[@Xielent]

I have the outlaw's with a H-Pipe, never had the Roush axle backs but the Flowmaster Outlaw is extremely loud and aggressive toned. Expect drone if you go with the Outlaw with a x pipe.

[@mistafivefivesix]

hey Bill, I just bought these from you guys and installed them Friday night. I have a small leak where the band clamps are. Yes they are in right orientation and yes they are torqued to proper spec. Is it common to have a small minor exaust leak where the clamps are?

[@Zerogivengarage]

+mistafivefivesix There should not be a leak at all, loosen the clamps and retighten

[@mistafivefivesix]

+Bill Tumas spec say 22 ft lbs. what is max torque? i emailed roush but have received no reply. if i can't get rid of the small leak will it mess up my valves? the pipe is fully seated and is cut perfectly strait

[@mistafivefivesix]

+Bill Tumas will I be able to put borla axle backs on with the same cut i did with the roush? can i just take off the roush and slap the borla on, or do i have to cut more off the mid pipe?

[@benjaminfrank_]

Are these to loud for the neighborhood,I need help finding something that's louder the stock but not to loud to piss neighbors off...

[@Zerogivengarage]

Depends on your neighbors I guess. As long as you keep the stock resonator they are not obnoxious.

[@alexistoledo4608]

Slp Loudmuth II is a good option for a deep tone thats louder than stock but not too loud either

[@thomaslenehan4341]

Will these fit on an eco boost

[@sbpdmike125]

hey Bill I just want to make sure this is a direct fit for my 2016 GT. I know you test fitted it on your 15 and the video says for both. Just want clarification. Thanks, your videos are great.

[@Zerogivengarage]

+sbpdmike125 Yes 15 and 16 are identical

[@Aiden550]

Is this louder than the borla s type?

[@gigi9467]

price difference between this and the borla stype? i know thats a car back.

[@danielrichard209]

Only mufflers with stock resonators and it sound that good? WOW !! Ford racing (borla) exaust come with the resonator deleted and it does not come close the the ROUSH sound ! Correct me if iam wrong but i think it's the best sound for a Mustang !

[@SALEHIII]

Already have rough axleback but I need a resonator delete should I go with met hpipe or ford xpipe

[@SuccessStream158]

+Salehlll I'm also looking for the answer to this. Have you recieved feedback anywhere else?

[@SALEHIII]

+smuvg I went with mrt h pipe ..... It's very loud but a deep tune .... U can control the sound..

[@DGGodzilla]

Will this exhaust void your warranty?

[@DavyDave1313]

Is there any difference between the GT axleback and V6 axleback other than the pipe size? I have a 16 GT, and upgraded from a 15 V6. I have the V6 axleback can I just put it on the GT

[@vahanparonyan3786]

what do you guys recommend on a 5.0 roush axle back, corsa sport back or borla atak?

[@hanstah9501]

what's louder? this or the bola attack exhaust catback?

[@h80282]

I love the Roush mufflers. But I don't like the cutting job it's not really clean job.

[@Mftater]

is this axle back available with black tips?

[@Zerogivengarage]

Roush is polished only but we have several others available with black tips.

[@Mftater]

Suggestions for a lower price range?

[@JCTiggs1]

Does anyone know the weight difference between the Roush vs stock mufflers? Also, what's inside the Roush muffler? Is it just chambered or is there some type of packing too?

[@ArthurSperotto]

The wheels changed from the stock clip to the aftermarket one!!

[@Zerogivengarage]

Yep. Since we can't reinstall stock exhaust for every install we use clips from the original exhaust. If you look closely it's even a different color car :)

[@孙毅卿]

Can I put my 2.3t roush axle back in to GT?

[@mohammadzaman8713]

Roush axle back or borla s type, What would be the differences?

[@zanumalik1591]

do we need to do any changes in engine to install exhaust pipe in car @cj pony parts

[@fiddybenz]

Zanu Malik you don’t belong near a car bro.

[@Kamal_AL-Hinai]

@@fiddybenz ikr lol

[@MartinM04]

Sounds lovely but the only thing I would change if I was to purchase this would be having the tip welded to the muffler enough said

[@deana6953]

is the MBRP Street Cat-Back Exhaust w/ H-Pipe - Stainless Steel better than the Roush Axle-Back Exhaust

[@Jacen777]

Does this mod impact fuel mileage in any way?

[@Zerogivengarage]

Only because you will hit the gas more since it sounds so much better!

[@corneluishickman8747]

Would it sound more aggressive with a x-pipe with it as well?

[@StevenNeidlein]

Yes bad ass sound

[@MRJordyshore]

does this work for 4 cylinder version? probably not right

[@myyusauce]

+MRJordyshore lol

[@challengerrt3455]

hahaha get a v8 so u can feel what is a real car 🙋

[@vinnievinnie5800]

MRJordyshore nop

[@77davidlara7]

I need advice? what should I get for my 2015 gt mustang, roush axle back or borla atak axle back?

[@Zerogivengarage]

+David Lara It's personal preference, both sound good IMHO

[@Mik3yDatBoi]

Roush.

[@milplayer17]

Will these work on v6??

[@ColdSid]

LOL

[@actuallyidc]

How do I get the crackle when I hold gear and get my foot of the gas? Is there like a particular kind of exhaust I should get? Thanks

[@Zerogivengarage]

The less backpressure you run the more likely you are to get a crackle. Tuning comes into play as well, richer tunes tend to have more.

[@mxrider887]

I'm looking for something comparable to the gt500 mufflers on my 2012. From the videos this sounds similar. What is your opinion on these two brands sound wise?

[@SuccessStream158]

I'm getting a Roush Axle back, does the x pipe sound better than H on the 2015?

[@chrishaugh1655]

Better is always subjective. They achieve two different goals. If you want a higher pitched, more aggressive sound then go with the X. If you are looking for the deeper, more throaty muscle sound then go with the H.

[@alextang8299]

why won't this one fit on the V6? they look the same.

[@cjponyparts]

Alex Tang It may look the same, but it definitely won't fit the same, nor will it function too well on a V6.

[@alextang8299]

ok gotcha. Thanks. by the way which exhaust system would suggest on a v6?

[@Anthfigueroa]

+Alex Tang buy a v8

[@bocho13mm]

+CJ Pony Parts I purchased these for my 15 gt and got a defective muffler the left one doesn't work it rattles due to how it was made. Anyways you guys didn't let me get the warranty on it and refuse to give me a single replacement or at least pay half price for one! I cringe at the sound of my exhaust because it rattles :/

[@a.d.4127]

‘15 V6 is 2.25” pipe. ‘15 GT is 2.50” pipe.

[@carrion1234567890]

Hey i just installed these and every cold start or if i rev up, the left exhaust rattles. it sounds like the tip but i tightened it as much i can and still rattles. Any solutions ?

[@Zerogivengarage]

+Marvin Carrion If the clamp isn't getting it tight enough you can have it welded but I have never come across that issue before.

[@wclutch]

Did you install it yourself?

[@carrion1234567890]

+Driv3n to Dr1ve Its fine now. it was a the muffler that was bad. Contacted roush and they sent me some new ones. its all god now

[@carrion1234567890]

+Marvin Carrion good*

[@KimberCustom21911]

Does this add any power at all?

[@cjponyparts]

It's mainly just for exhaust note.

[@drewg3839]

is it possible to install the Corsa extreme double x pipe with the Roush axle back? if it is will it sound louder compared to just the Corsa extreme only?

[@cjponyparts]

Never tried it but I can't imagine it would sound much different.

[@devv8]

How much HP does it add?

[@cjponyparts]

Axle back exhaust will add very little, its mostly for sound.

[@luki8833]

Hi, which option would you choose from x pipe or without x pipe (stock). I mean a nicer deeper lower bass tone. The xpipe will be louder but will not the sound be higher than the bass? Thanks !!

[@raychow1272]

The sound clip Roush showed of the axle backs was terrible.. Got me scared for a second thinking it sounded like a v6, but your clip is true v8 sound.

[@Threefiddyz]

if you got this axle back and cut out the resonator and put an xpipe or h pipe in would it or should it drone?

[@Prophylatix]

Yes. Any time you remove a resonator from an exhaust system you will have drone. Resonators buffer the sound from your engine during your engine's "loudest" frequencies. If you remove them, you have nothing to buffer the frequencies, thus allowing these frequencies to cause what is called "drone." It is simply a matter of whether the drone level is acceptable or not to the driver.

[@Zerogivengarage]

We will be installing a resonator delete with the Roush system in the next few weeks and will do sound clips on it. While in theory above post is correct about the purpose of a resonator, not all systems drone just because you remove it. Certain mufflers do an excellent job at limiting drone, Borla has worked hard on that for years. The Ford Racing/Borla systems we installed had no drone at all at highway speeds.

[@Mfrancojr]

Bill Tumas much agreed installed the Ford racing x pipe with stock mufflers and zero drone. In fact I can barely hear a difference inside at idle. But outside its better, and according to people who hear it from the outside its a huge difference.

[@gabrieltorres713gt]

Do you get crackles and pops with this one?

[@Zerogivengarage]

You will get some yes, a resonator delete will be louder and have more.

[@elche2124]

One quick question this fits on 2018 ecoboost premium 201A

[@montyhades]

Could I be able to get something like this for a 2005?

[@borqnafurnadzhieva6485]

I love missing YOLO

[@VentusMaster123]

American turbo yoda

[@betherealdeal]

I heard that Rousch mufflers rust quite a bit made in China junk Is this true?

[@Zerogivengarage]

No.

[@Prophylatix]

If you're concerned about rust, you can always powered coat your axle-back. Eventually, you will have surface rust on anything stainless.

[@betherealdeal]

I made some research on this issue and found that most mufflers including OEM are made of 409 type of steel which has less chromium. Borla has 304 steel which has high content of chromium. They last longer and cost more.

[@bhogal97]

Could you add a x-pipe and headers to this system?

[@Zerogivengarage]

Yes absolutely.

[@cjponyparts]

Many of you have been asking about the Roush exhausts for the 2015 Mustang. Roush Performance sent us one, so we can bring you a full installation video and sound clips! Now available for Pre-Order at CJ's! www.cjponyparts.com/roush-axle-back-exhaust-stainless-steel-gt-2015/p/CBR19/

[@jallahellason4316]

Can this exhaust be welded on instead of bolt clamped?

[@themambaification]

I'm curious I've seen a good bit videos of exhaust and I'm trying to find a nice loud exhaust and when in neutral still be able to hear it.. what exhaust is recommended?

[@jamesfuller5182]

Yes it can mine is welded

[@tri3pleagent]

The Ford Racing system sounds much better.

[@Nosettrippin]

In your list of things needed, add ear plugs :D

[@wclutch]

Get an x pipe with the roush axle back. Then you'll need ear plugs lol!

[@Nosettrippin]

+Driv3n to Dr1ve lol!

[@corneluishickman8747]

And would the roush fit any model between the 16 or 17 ?

[@Abdulmalik_5535]

Hi what do you wish with good sound borla s-type or Roush or Borla Toruring ??????
