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 ...

Poor fit

Weld brackets on pipes were not in proper location making it impossible to obtain proper fit

Will this exhaust work with bbk long tube headers and shorty x pipe?


  • Axle-backs do not mount directly to the mid-pipe so you can absolutely use this Pype-Bomb without any issues in combination with the BBK LTH and Shorty X. Hope this helps!

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.

    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 :)

    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.

    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.
