HP gains? About how much hp do you gain with this exhaust?


  • I bought them and put them on my 2013 v6 you break it in a lilttle bit you can really notice how quick it makes the car when you put the gas pedal down far makes the nicest sound horsepowee should be somewhere around 10..... If this exhaust didn't add any horse power the sound is still worth it. The only problem is that the tip touch the body of the car aliltlw so im going to have to adjust that some how Iv seen other AM customers with the same problem.

Exhaust system for my 2012 V6 Will items 56116, 50178, and 20127 go together and would I need any other parts?


  • The BBK Long Tubes (56116) will fit your Mustang as well as these Pypes Axle-backs (20127). The Cut and Clamp (50178) won't be compatible with the long tubes though as they are designed to reuse your stock cats and attach to either stock manifolds or shorty headers. With the BBK LTH, you would need to use the BBK Catted or Off-road X-pipe. Nothing else would be needed but we do recommend a custom tune with the LTH to obtain maximum performance gains. Hope this helps!

Torque gains? Curious if anyone noticeable gained any torque.


  • No,Im pretty sure axle backs alone even deletes are not going to make a noticeable difference.I would suggest replacing your intake and or throttle body if you want some noticeable and dyno proven gains in the lower spectrum torque and hp

  • I have a 2013 V6 with axal-back pype-bombs, and the sound is close, but the pypes are a little louder and have a more aggressive sound, and are $200 dollars less, but very well made.

    Amazing sound

    Fitment is not good. Hard to get the pipes to line up, also once they're clamped on they don't really sit right. Just had mine installed and the drivers side looks good, but the right side looks like it's hanging down and to the right. Took about 30 min start to finish, and the sound it makes is completely worth the struggle with install. Amazing sound, not v8 sound, but these things scream like they're ripping holes in the universe at full throttle. Lots of crackles and pops too which everybody loves :)

    Very good exhaust tone and yes it is LOUD. However it is not to loud. The most flow and great exhaust tone for the best price. Guy in my apartment complex stopped to ask me what kind of system I had bacause he liked it better than his Borla ATAK. Althought I think the Borla systems are great to, there is a big price gap there and the Pypes Bomb sounds just as good if not better. The only problem was with AM shipping. I paid the exrtra money to get them two day air and they came 2days late. Have not got the money for the shipping back. Seams like giving the money back for the shipping is the right thing to go. We will see what happens. Still great product for the money. Recommend them highly.

      It do see that the credit was processed already but depending on the bank, it can take a few business days to show up on your statement. My apologies the package didn't arrive on the specified day. I assure you that's an extreme rarity, but of course we'll make things right if that situation ever arises. I'm glad to hear you're loving the new sound of your Mustang with these axle-backs!

    The way a Mustang should sound!

    The instalation took about four hours with two people. The stock mufflers were hard to get off but the Pypes were easy to put in. The tips of the Pypes are not on center with the bumper cutouts where the tips go but thats ok for now... Sound: these are loud! ver loud in the lower rpms. a huge difference compared to stock. when I get to about 2500 rpms the drone is absolutely terrible. i try to avoid that area or get through it as soon as possible. above 4000 rpms the Pypes are hard to hear, maybe becasue of my Airaid cai but i dont know. overall if loud is what you want then get these! i will enjoy these for many years to come! I just hope the neighbors are ok with it, lol!

    Great sound, didnt fit rite

    Once i received these, i was able to install them in just about an hour. However they did not fit properly, the tips were touching the bumper cutouts, so i was forced to take it to a shop. They had to weld stoppers on the exhaust hangers to keep the tips as center as they possibly could. $50 for the fix. Good quality product, deep agressive tone with little drone and less pop but they just didt fit rite. Still the cheapest out there for Axelbacks. This is Pypes fault, not American Muscle. I absolutely love American Muscle, for their reliability.

    best exhaust you can buy

    This is the most free flowing exhaust atleast formy 2013 v6. So its the loudest most agressive exhaust for the cheapest price whats the catch? Some people dont like loud fierce sounding exhausts that make a muscle car what it is. So if you want to go spend double the money on an exhaust that very slightly changes the car sound then you should just go buy a prius because muscle cars are suppose to sound mean.

    Great Exhaust... Interesting install...

    This set of axle-back exhaust is overall quite wonderful. When it comes to the sound, it does sound absolutely wonderful when you're punching it. at the very low RPM's the sound can be a bit underwhelming. almost like a honda civic with a can on it, but it's honestly not bad at all! the install itself was odd. the first one went in without a hiccup. the second one, however, had issues. the hanger rods were not properly set to go into the black rubber hanger mounts (which needed to be approximately 7.5 inches wide, and the pypes' hangers were at 6.5). so i had to bend the hangers after a phone call to americanmuscle confirmed this was somewhat normal to do. then i found they were angled incorrectly, and i had to keep bending, try to install, see if it fit the mid-pipe, if it didn't, repeat until correct. this added about 40 minutes more than necessary. additionally, as others have stated, the tips don't line up perfectly with the exhaust holes in the bumper and need to be bent around. i may need to go to a shop to have them get it perfect. i really like this purchase, i do recommend it, i just wish Pypes was a bit better about ensuring fitment was correctly prior to shipping. also, why no instructions? at all. like nothing! i had to research all online since I was new to exhaust installs. as others have stated, 2 people is HIGHLY recommended to install. and finally, yes there is a drone at about 2500 RPM, but you'll never be hanging around that level. you should either be shifting if you're calmly driving by then, or blowing right past it if you're driving hard. so no worries at all. for the money, this was good stuff! i'm also attaching a video that i recorded with my cell phone. hope it helps some people.

    I thought at first that the exhaust was too loud but it took 40 miles to break in. It sounds great. My description of noise through rpms. Idle 800 quiet sounds like stock great for when you need it to quiet. 1100-2800 perfect just loud enough. 2800-3000 slight drone. 3000 to redline sounds like you are ripping a hole in the ozone layer. Real attention getter. Love it, no complaints. Four inch tips are just what was needed to give my stang that aggressive look. The stock exhaust was such a let down with those barely noticable tips. What more can you ask for. In conclusion, best bang for your buck and would have been sorry gettting anything quieter.

    product is excessively loud and has obnoxious drone within the cabin. i almost had it removed right after i had installed them. i gave it some time to break in. it is now 400 miles since i have installed the exhaust and the drone is gone. the exhaust has is now pretty quiet at idle and highway cruising. but punch it and it sounds like a monster. it does not quite sound like a v8 but definitely doesnt sound like a v6. it is in a class in its own. truly the best mod i have made for my mustang.

    3.7 V6 PYPEBOMBS!

    i just got these and installed them myself on my 2012 v6. i will tell you its a two man job cuz its REALLY hard to get the exhaust lined up in the bumper because the connector on the exhaust isnt easy to get onto the midpipe. it fits but you really gotta work with it to hold them together AND tighten the clamp at the same time. now for the finish, the pypes look amazing...welds are nice, nicely polished, they do look good on the car just need to be adjusted. "SOUND". i took off a set of flowmaster force2 axlebacks and the pypebombs are louder and deeper with less tinny popping after a rev. they do drone a little but not to bad

    Extremely Unhappy with Pypes Bomb

    I had researched this exhaust thoroughly prior to biting the bullet and purchasing them. Online sound demonstrations sounded pretty good and I wasn't too worried about all the fitment problems I read about. I was expecting there to be minor fitment issues given all of the reviews I had gone through but I wasn't anticipating it to be as bad as it was. Me and my mechanic tried a few different things before we decided we just had to cut and reweld the hangars to get the exhaust to fit properly. Prior to that, the exhaust was rubbing heavily towards the side of the cutout in the bumper. After all was said and done, we got it to fit, but just two days after install there is an unbearable rattle coming from the driver side. I've given it a look myself but can't determine exactly what is causing it so I'll have to go back to the shop and get them to fix it. As for the sound, maybe Pypes sent me a different pair of exhaust but to me they sound like a Japanese import with a can on it. Add to that, from take off it sounds like a kid is behind the car ripping wet gas of some sort underneath all the noise. Definitely not the sound I was expecting nor the sound I wanted at all. Overall, very unhappy with the product all around. I will most likely be getting rid of them and just getting a pair of GT Take-offs.

    • Response from AmericanMuscle

      It sounds like the muffler itself is defective within the resonator possibly. I would highly suggest contacting Pypes directly, as they prefer to handle all their warranty claims. They should be able to get you a replacement set that should both sound and fit much better. If you continue to have any other problem or need any further assistance from us, please do not hesitate to give us a call.

    quality product great fit with a crisp look.

    after reading all the reviews on the site and being 70 yrs old i had it installed by a shop as the reviews all said it was easier with 2 people. i did not want to involve my neighbors and be flat on my back on the floor , i feel i made the right choice. the task was completed in 40 minutes with the car on the lift. i held and help position the mufflers and assisted in any way i could. i could not be happier. they fit great and look good. the shop was as impressed as i was with the quality and fit. i am so glad i did not install myself because being under the lift and working together you can adjust and create the perfect install and avoid all the problems.. money well spent.

    V6 Pypes Review and Installation

    Loudness: Once the installation was complete and I turned my car on the look on my face describes it all. Owning a V6 you don't hear the silent stock exhaust but with Pypes you hear everything. It definitely sounds like a V8. Exhaust Note: There is a pretty decent amount of drone from 2500-3000rpm. You may find yourself changing the way you shift to get around this. I have also not noticed any popping as of yet and if I do I will update my review. Fit & Finish: The passenger side went on just fine, slightly closer along the outside and trying to center it was proved fruitless. The driver side was a different story as it is all the way against the outside hitting the bumper. We tried several installation methods like holding the exhaust in place while it was tightened and it would just move back to touch the bumper. It seems like a lot of people have this same issue so I will be contacting Pypes for some recommendations (Possible a new mounting bracket). Bang for your Buck: Pypes has a great price on this performance exhaust and you can't beat that. Installation Time: A buddy and I learned the hard way on how to install these exhausts taking about 2.5 hours. Ultimately this is how I recommend performing the installation: 1) WD40 the brackets and let it sit for 15 or so minutes. 2) Lift the car and remove the mounting bracket closest to the bumper. 3) Loosen the clamp holding the stock axelback 4) Remove the three screws holding the mounting bracket to the bottom of the car. 5) Once the exhaust is taken off you can simply bend the clamp a few times and the tab will break off. 6) Put the mounting bracket on the new exhaust. 7) Put the clamp on the new exhaust. 8) Put the exhaust in place and tighten the three screws for the mounting bracket. 9) Align the mid pipe and the axelback together. 10) Tighten clamp enough to prevent it from detaching from one another. 11) Mount the bracket closest to the bumper. 12) Tighten all bolts. Repeat on the other side. Following those steps will save you lots of time, trust me.

    Worth the wait!

    So here are my impressions. They're pretty awesome and very loud. They have a deep idle and sound great through the rpms. Some things that I can live with though is the fact that there is a very noticeable drone at 2500 rpms, as in the whole cabin booms. But hey, they're flow through mufflers so it is somewhat expected. The second thing I can live with is the alignment. They aren't dead center in the cutouts but honestly it doesn't look bad. Anyways, I love them and I'm very glad I waited for these to come out.

    If Loud Is what you are after

    OK I was looking at these and wondered why half the price of other Axle-Backs, these are muffler deletes so you cant really compare them to other setups that are muffler upgrades or replacements. That being said I ordered them at $319 and the price seems to bounce down to $289! I wish I waited or caught them at the cheaper price! Hence the two stars. Also there was a metal-to-metal type scratch inside the protective shipping plastic. Someone at Pypes Quality Control said "Since this scratch is on the underside -side of one exhaust no one will see it." So far over-paid $30, a scratch..oh yeah someone with a marker wrote the words "I lay" and an arrow over to the words "Pypes" on the box. I thought it was funny but no one else did. Now a $30, a scratch, and a joke. So I installed these in about an hour with ramps. The pax side went on slightly canted so to make things easier loosen the mid-exhaust bolts, make a good fit, and tighten form the pypes forward. So even though the pax side was slightly off there is was leak, however the driver side went on perfectly but touched the bumper. Correct fit for these are about an inch from the outside bumper. I re-loosened the drivers side, placed a cloth between bumber and Pype and re-tightened everything and that corrected the issue. I started her up and these are LOUD. You can actually hear the engine. My neighbors say my Mustang is "healthy" now. Pypes designed the sweet spot right at 1800 - 2200 RPM. Above that you will not hear them anymore. But cruising down your street, or stuck in traffic, people will definitely hear your exhaust. Note the word "bomb" in the name. If you are used to the stock exhaust these will seem too loud in the cabin at first but after a while you realize the quiet exhaust was the unnatural sound and personally I enjoy hearing the exhaust note, and it is not so loud you cant hear the radio. So for the loudest exhaust note Pypes made a no-frills muffler delete that will get you where you want to go way cheaper then the competitors you cant go wrong.

    Overall it's a good product

    As i have read in other reviews that these do not fit well and line up correctly. Which of course mine did not. I will have to take it to a muffler shop so they can bend them because the drivers side touches the bumper. I assume it will b a $50 shop fix. But overall great product. They were cheap and they weigh half the weight of the stock mufflers. The stock mufflers are a pain is the butt to get off. It is definatly a 2 person job. I would recomend just cutting of the tabs that connect them, which is 10 times easier. But it is possible to work them off. The sound is amazing!! They are loud!! It took me a little while to get use to them but you get used to it. Its not quite a V8 sound but will make your mustang sound like a muscle car!!!!

    2013 V-6, These pipes are LOUD!!! Definitely sounds like a monster. Install was about two hours to get them aligned good enough. The drivers side is more difficult to align, do yourself a favor and loosen the clamp on the drivers side mid pipe. They are not centered but look good. When I first started the car and test drove it I had mixed emotions about the loudness but it seems to be quieting down a bit and starting to sound much better. The drone is what everyone else is saying on the reviews. I think I will be saving money on gas as when you step on the pedal it growls like a lion right next to your ears and I tend to baby the gas to keep it quieter, I know why the heck did I buy them then? Well I wanted to wake up the Mustang, mission accomplished, I am Turning 40 in a couple of days and I feel like I am 16 again!

    Great exhaust for a great price

    This axle back is hands down the best mod I've installed on my car yet. The install was quick and easy and the price is great. Using hand tools and without a lift I was done in about 45 minutes. The Pypes fit perfectly in the bumper cutout. As for the sound, the videos on YouTube don't do this exhaust justice. I absolutely love the throaty roar my v6 has now. Idle volume is perfect, not too loud or quiet. From 1000 to 2500RPM the exhaust note is great. From 2500 to 3000RPM there is a slight drone, but is bearable. From 3000RPM and up that's where this exhaust comes to life. Definitely doesn't sound like a v6 anymore. I'm about halfway through the 400 mile break in period and have yet to have any issues. Absolutely love this exhaust. If you're having second thoughts about buying this axle back, don't just get it. Totally worth every penny.
