Will this muffler fit a 2013 Mustang V6 Automatic? I want to be absolutely sure about this before I buy.

  • Actually it will - just mounted it on my 2013 V6 within 20 minutes only. You may just need new clamps (which are not a part of Axle-back delivery) but even stock ones (if not too old) can be used easily.

i have this exhaust, a v6 2012 automatic, and airaid cai,bbk 73mm throttle body,bbk catted xpipe, bbk chrome long tube headers, and a race tune. is this setup restricting my sounds like the car is holding back a few breaths and when gear changes, the sound whistles or hisses, so much that it messes up the regular sound, and gets louder then the regular sound. why is this, does anyone has this combination or a similar one that has worked better?

Most of the people that wrote reviews for this exhaust agree that it's a nice deep sound with no drone, and they are very happy with it. However there are three reviews that say that this exhaust with an automatic trans is horrible... is this true? I have an auto and i don't want to get this if it's true. Also what would make this exhaust worst than other exhausts for auto trans? Doesn't make sense to me. Thanks

    Wooooooooo........ What A Sound

    Wow.I'm impressed. After weeks of listing to exhaust sound bites and seeing video clips on youtube I went with Magnaflow street series. They sound great.They are slightly louder then stock at idle but Between 1500-2500rpm that is the sweet spot. Thats were they sound the deepest and mellowest like a v8. Nowhere in the rpm range do they sound like a import tuner. I should know I have owned 3 Nissan 350z over the last 6 years. Above 2500rpm they keep a nice deep tone ,but they are not overly loud. Also there is no drone sound in the cabin so you can hear yourself think about how cool it is that you own a Mustang. I strongly recommend these to anyone looking for a deeper more v8ish sound out of there v6 mustang. Also I would recommend a Bama tuner,C&L cold air intake and a throttle body spacer. all of which I have bought from American Install start to finish took me about 1 hour. You can Download the instructions from the Ford Racing exhaust page.That's what I did. It made the install way easier.

    DEEP and melow

    I looked at lots of systems, and listened to dozens of sound bites and a few in person. I knew I didn't want droning popping sounds like flowmaster or to sound like a Japanesse tuner. After Installing these I can't believe how deep they sound, not raspy, no pops when you let of the gas, it just sounds like old school big block power. No real instructions, and you have to reuse the clamps on the stock system. After the main chore of getting the old ones off these aligned up nice and easy, both were dead center first shot. Love them, get these!

    Installation Experience

    I have found that the reviews at AM have been very helpful and I want to return the favor by addressing some uncertainty that I had before my installation experience. I have a 2011 V6 which had under 4K miles at the time. 1. You will note that some people had an easy time installing the Magnaflow Street in under an hour. Others like myself took an entire afternoon- 4 hours. The probable reasons for the different time requirements are due to whether the installer obsesses over the details and whether it is difficult to get one or more of the pipe tips aligned in the cut outs. My driver side pipe alignment was out of kilter and I had to undo all the hangers to get some play and still muscle the pipe into alignment while I tried to tighten the band clamp to hold it in place. So there is a luck factor in play. My passenger side was much easier and quicker. 2. I did have to remove the two bolts holding the driver side of the black cross-member to get enough room to get the driver side OEM muffler out of the front rubber hanger. The driver side is where the pinched fingers occured. 3. Plan on using WD-40 on those black rubber hangers. It is really hard without it. 4. The band clamps are tack welded to the OEM muffler for a reason. It is so they go on straight and seal properly. You will have to cut or bend them off to reuse the band clamps. That is pretty quick process with a hacksaw. But without these being tack welded to the Magnaflow, it is much more difficult to get them so they are not canted when you install and tighten the bolt. 5. The most difficult part is getting the OEM driver side muffler off. That is when the cursing began. The Magnaflows are much lighter than stock and because of the way the prongs for the hangers go, it is much easier to install them than to take off the OEM. This will only take a few minutes. 6. As I indicated, I was one of the unlucky ones who had one pipe (driver side) pipe off kilter. It took me a couple of hours of adjusting (pulling, twisting etc) to get it somewhat centered in the rear valance cut-out and so that it looked aligned with the passenger side. The only way I could do it was to have the clamp somewhat canted. It is canted enough that it hits the tack welded on lip of the pipe, but it still seals properly. So there you have it. Was the effort and cost worth it? In a word, yes, but I am glad it is done with. The sound is perfect as others have described. It is just a tiny bit louder than stock at idle, but it has a really nice throaty sound on acceleration and I experienced no drone. I have not found any pops that some have complained about. I suspect those pops may be due to people not having it on properly clamped and having an air leak before the muffler which reduces back pressure too much. Hope this helps!

    Sounds excellent

    Just installed these mufflers on my V6 2011 mustang - you will not be disappointed...they wake up the v6 and give you that low rumble you need. Not too much just enough a little louder than your stock mufflers and when you step on it ...sounds excellent. The videos do not do justice for these you got to hear them in real drone, sounds great and gives you that muscle car tone you want. Highly recommend these mufflers to all V6 owners...Thanks American Muscle for the advise on the phone and the quick service you provide. These were easy to install about 1 1/2 hours for me....wear gloves you will need it or forfiet cutting your hands like I did......Cheers

    I own a 2012 Black Mustang V6 mustang club of america edition, with the performance package and I just love the car. The only problem was that the exhaust note was ok but it really lacked that mustang sound that I wanted. I looked high and low and did way to many hours of research on the internet and the pro shops around. I was going to go for the Borla Atak system because I heard great things about it and hey, something that cost more then the rest must be good and they are a fantastic company. But I really didn't like the pop noise and it just didn't sound deep enough for me, so I checked out the Magnaflow Street exhaust and instantly I fell in love. The order from American Muscle was so easy and the person I spoke to was amazing and so professional. I love this exhaust and it is exactly what the 2012 mustang v6 should sound like. Wow is an understatement.

    2011 3.7L awesome sound

    Just bought a 2011 Mustang V6. I wanted a more aggressive sound so I initially tried the Flowmaster Force II axleback system and it was... okay. The only thing it did was change the tone a little bit to sound more like a Nissan 350Z. There was also a popping noise with both the stock exhaust and the flowmasters when you revved the engine up any higher than 2500 rpms. Everyone told me this was normal and would occur with any exhaust system. I decided to give give these magnaflows a shot and i couldn't be happier. Sound is slightly louder, not obnoxious. The tone sounds like a stock gt especially in the lower rpm range. the car breathes a little better and best of all, no more annoying popping noise when you rev it up. Easy install and the tips look great. Highly recommend this system if you want a deep exhaust tone similar to that of a GT. I've had many guys come up to me thinking it was the 5.0

    Great at full throttle, not so geat with normal driving

    Fit and finish are top notch and sound at WOT is fantastic. Everyday normal driving with these mufflers drove me crazy. If I had a manual transmission, they may be ok, but the constant shifting of the automatic and the droning at low rpm was too much. I've removed them and put the stock mufflers back on.

    These mufflers sound great

    I installed these mufflers this weekend. The directions from Magnaflow are very limited and incomplete. There is a strap spot welded on the ball and socket clamp that must be broken, in order to remove the stock mufflers. Also,there are two hangers that hold the stock muffler to the chassis. To remove the rod from the hanger nearest the tailpipe, slide the rubber isolator off the muffler hanger rod. I used two large screw drivers for this. The other hanger is more complicated to remove, as one would need to slide the stock muffler forward to remove it from the chassis. A better method is to remove this hanger (there are two to three bolts which fasten these hangers to the chassis). The most difficult fastener to remove is in the center of the hanger. I used a 1/2" combination wrench. Putting on the Magnaflow exhausts is much easier, as the hangers on the muffler aid in installation. They point towards the front of the vehicle, which is the way Ford should have done with the stock mufflers. I used a strip of cardboard, folded up and stuffed between the muffler tip and the body to make sure I had enough clearance, and tightened the ball & socket clamp. The tips look great and the mufflers sound great. I highly recommend these mufflers.

    I listened to many exhaust systems and read many reviews on-line before making the Magnaflow choice. My V-6 has such a wonderful throaty 8 cylinder sound now. I am very happy with the purchase. It did get slightly louder after about two weeks of driving, but definitely not obnoxious. This exhaust was the best aftermarket thing I've ever done to a Mustang.

    Easy install, great sound

    It's more of a personal opinion but if you don't like the popping noises most of the other exhausts especially the critically acclaimed atak make, this exhaust is for you. It's really low but not to loud up to 90 mph. I installed it without even jacking the car up... never thought not having lowered the stang yet would come in handy. Hardest part is cutting the seal on the stock exhaust... I tried for 15 minutes using leverage to break it until I crawled out from under the car and fetched the dremel.
