Review & Install Video

Hi everyone I’m Justin from, and I’m checking out Pypes performance pype bomb series axle back exhaust for your 2011 and up Mustang GT. Pype bomb is a very fitting name given the aggressive tone this axle back gives you, that is due to the fact that this kit uses muffler deleting resonator tips. The kit is constructed from durable 304 grade stainless and features 4 inch fully polished tips, which allow for superior looks and corrosion resistance. Install is very simple and should only take you about an hour using standard hand tools. Let’s hear how the pype bombs compare to your factory exhaust.

Aggressive Sound. Give your 2011-2014 GT the aggressive sound that will get it noticed on the street or at the strip with a Pypes "Pype Bomb" axle-back. This muffler delete style axleback provides the most aggressive, free-flowing exhaust possible with your factory cats still in place - delivering more power you can feel and hear.

Resonator Tips. The engineers at Pypes designed their new muffler delete exhaust system with specially engineered resonator tips that eliminate that loud annoying popping noise that other muffler delete kits can cause.

Polished 304 Stainless. Unlike even some more expensive exhausts, this system features a fully polished finish for superior looks and corrosion resistance. And with its 304 stainless steel construction, this system will last just as long as those costing many times more.

Application. This Pype-Bomb Axle-Back exhaust system is designed to fit 2011-2014 Mustang GT for show quality looks and impressive sound. This axle-back is made to be a direct bolt on to the stock location without any modifications required.

Power increase? Will these muffler deletes provide a noticeable gain in HP? If so, would it be more or less than a muffler delete without resonators?


  • I purchased the Black ones that just came out, OMG the sound a lone is good enough for me but I have to say yes there is a power gain, a lot less restrictive and a lot less weight on your rear-end of the Stang, the LOOK is great as well.

factory clamps? Do these come with clamps or do you use the factory clamps?


  • You are able to use the factory clamps. You can use a cutting tool like a dremel or angle grinder. I just moved them around back and forth and the clamp came free from the factory muffler.

i was gonna be these for my 2010 mustang gt and i wanted to know if these deliver more power to my mustang i also have a bigger body throttle if they makes any difference to the sound and power to it


  • Certainly by opening up the exhaust, you'll get more power. Don't know if it will be power you can feel right away, but it most assuredly give you a more aggressive sound.

    Best After-Market Exhaust

    First off, if you are buying a 400 hp V8 I have no idea why you are complaining about noise. Buy a Dodge Charger if thats the case. Secondly, the sound on this exhaust is AMAZING. My friend spent 800 bucks on another brand and it does not sound nearly half as good as mine. Its not an annoying loud exhaust, it is a loud, mean, american muscle sound! If your looking for quiet, you shouldn't have got a Mustang. Great price, great shipping, and if you put up on a lift installation is simple. Do not try and install while on the ground. It can be done; however, it will make it more difficult to adjust it perfectly. The drone is not "terrible" with 3.73 gears. If anything the car consistantly puts off a mean sound that will turn heads. Please, do not turn away from this exhaust from people complaining it is too loud they shouldn't be driving muscle cars if they want their stangs to sound like a Toyota hybrid. I have also owned this exhaust on the 2010 Mustang and it was amazing as well.

    I received my Pypes Pype-bomb mufflers in 3 days. The installation is very easy with a 1/2" spanner and socket. From start to finish it took 45 minutes. The sound is RIDICULOUS! At 2000 rpm it growls. At 7000 rpm it sounds like Godzilla. But, on the highway there is no drone. This is exactly the sound I wanted for my 2011 GT Premium. The car shifts easier now with less hesitation between 1,2,3rd gears.

    Amazing Sound

    I have an SLP's Loud Mouth axle-back system on my 08 Mustang GT, and this Pypes axle-back sounds better IMO. I am not going to say it sounds a lot better, but I do believe they are an improvement. It sounds great when you step on it and I have no annoying drown on the highway. I got my package from AM in less than five days and had a local shop install them the day they arrived, took them less than 45 minutes. They have a great look that is only outmatched by their sound. When I first pulled out of the muffler shop and stepped on it a bit, it made me smile and giggle like a kid. Great product and a great price.

    All I have to say is amazing!! I do not review products often for the simple fact to allow others to develop their own opinion about products,but this product required me to give a review. Of all the Mustangs I have owned, and all the exhaust systems I have installed, this system by Pypes is standalone the all time best!! You have to see "hear" it to believe it!!

    Pypes System

    Avoid this system if you have 3.73. The drone at 2k rpm is terrible. Start up and daily driving it sounds amazing but drone on highway kills it. Bought Borla ATAK and it's just as mean with no drone. Spend the extra, it's worth it

    At first I was a little hesitant about buying these because some people said the drone was bad, but I have a 2011 GT500 Cobra and it sounds just like a muscle car should with little to no drone at all!!!!! These are the best sounding mufflers on any of my cars!!!! And I highly recommend them if you want your hot rod to sound great!!!!

    I installed these mufflers myself on my back in the driveway. Instruction are included and I only needed a few basic tools. The sound is much deeper and louder than stock. The fitment is not perfect. I did a second install with a friend and fitment was perfect. This is the best value for a new mustang out there. Like my summary says these are LOUD!! Dont delay buy today.

    No need for SLP.

    Overall a fantastic product, great looking tips, high-grade metal, and amazing sound. The only reason this product doesn't get 5 stares is due to fitment. As with most bolt on systems there will be fitment issues but mine actually had to be cut and have new pipe welded in order to fit correctly, with that said it did cost 139 to have them installed which added to the price of the product is still the cheapest rout to go. The sound from these are without a doubt amazing, I was standoffish due to really wanting the SLP's but couldn't see pay 500 for an axle back alone, but there is no need to fear the resonators due very good things in reducing the annoying pop to the standard of cool and not obnoxious where the SLP's are. After it is all said and done find a good local shop and get them to install, if you live in atlanta go to andy's muffler in Snellville ask for nick or andy and bring an extra 150 because they will build and install an x-pipe for you and it sounds, looks, and fits better than anything you can buy. So great product very loud and very good rumble, the drone at 2k I think is cool and with the windows up and the stereo on hardly noticeable until you give up trying to contain your led foot.

    Sounds great, install was horrible

    PROS: the exhuast is a monster! Makes you feel like your driving a super sports car down the road. Even when you turn it on it's so load it sets off car alarms. Going down the street in the high RPM's it's insane how nice it sounds. It's a head turner for sure. CONS: The box it came in was so smashed up I could see the exhust sticking out. Lucky it was wrapped up really good. The really bad part is the install... I took to my dealer ship and they put it on but they said the pipes where at a weird angel and it didn't fit right. It was so off it was rubbing against the car. I had to take it to a muffler shop and they asked me if this was even the right mufflers for my car. They had to cut some of the exhust to get it to fit properly. All in all cost me a little over 150$ to get this exhust on. I'm disappointed in the fact that a bolt on would give me this much trouble. I feel like I should be refunded that money.. Anyways all in all if buy it again just for the fact it sounds great!! Just remember that you may have to spend some money if u want it to fit right.

    Sounds Excellent

    I love the new sound my 2013 Mustang GT produces. Only downside is I received one of my pipes with about a inch gouge near the edge of the tip. It is noticeable, but I already had it all mounted and bolted down prior to taking the bubble wrap off, so it was too much of a hassle to take it off and then get it replaced. Love the sound though. Just like a Mustang should sound....Loud and throaty.

    Roaring like a lion

    These pypes are awesome. It is very aggressive when I put the pedal to the metal. It purrs like a kitten at idle and roars like a lion when I punch it. You cannot go wrong with this product. I highly recommend if you like a real mustang. I installed both sides in a total of 25 minutes.

    Poor Fitment....Great Sound!

    This product produces a great sound especially when paired with the BAMACAM. The downfall is that the fitment and alignment is terrible. They leak at the ball joint. I have tried several solutions including re-adjusting the whole exhaust system.

    Great idea and price point - poor alignment

    Go ahead, thumbs-down me if you'd like - but here's what I would have liked to have heard prior to my purchase: On the 2013s (at least) the tips stick out 2-3" LONGER than the stock exhaust. couple that with a more "squared off" cut of the pipes, and the look is akin to driving a 1987 Camero Berlinetta. While the chrome was in nice shape and the pipes themselves were good quality, it required me to loosen the mid-pipes to get the angles of the exhaust correct - but nothing (aside from having an exhaust company cut the pipes) were going to tuck them up under the bumper any more. I didn't have this problem with a pair of GT500s my friend bought and we mocked up on my car...they just weren't loud enough for my taste. Should have shelled out a few more $ and went Roush... In short, great sound, poor engineering. I think Pypes need to take another look at the 2013s for how they fit and adjust accordingly. I will eventually swap these out - but for now, they'll have to do until fund free up. Disappointed.

    Agressive sound!

    Awesome sound! If you don't like it loud I would suggest something else. This was my first exhaust install, so it took me approx 1-2 hours to get the drivers side stock exhaust removed and Pypes installed (using stock tire jack). The passenger side took less than 30 minutes. I found it easier to remove the entire bracket and hanger instead of only removing the hangers (even using WD-40). Fitament took a bit of adjusting, but finally fit perfect. Be aware the clamps are welded to the stock exhaust and have to be cut off (bust can still be used with the Pypes). I love the sound and have received may compliments the last few weeks. There is a noticeable drone at 80mph in 6th gear, but not too bothersome. I also installed the AMR Charcoal staggered 19in rims and Pirelli tires...looks tough!

    This exhaust does sound great...but I was very disappointed on how it fit. Never wanted to just bold on and be even! Struggled with it for hours trying to get everything to fit correctly. There was also two dents in the tip, not the kind of product quality I expected.

      Sorry to hear that you had difficulty lining this axle-back up during installation. As for the tip dents, unfortunately things can arrive damaged once in a while, knowing how rough delivery services can be with packages. Please give us a call if you'd like a replacement shipped out to you!

    Before I installed these, I ran my car with open over the axle pipes. After I installed the Pype Bombs, the volume of the exhaust has stayed the same, but I literally have to holler at my passenger at almost any RPM or speed so they can hear me. The drone is 2-3 times worse with this axle back than with the dumped open pipes. Nice quality and beautiful looking tips, but terrible drone. (2011 GT Auto w/3.15s)

    Pypes Pype-bomb Axle-Back Exhaust (11-12 GT)

    This is the 2nd set of Pype bombs that I have installed. The first was on my 2006 GT and most recently on my 2011 5.0 ... I thought they sounded great on my 2006 and I think the tone is even better on the 2011. The tone is deep and aggressive and there is no "popping" like I've had on other brands of exhaust. The exhaust looks better than the example photos given and much, much better then the factory exhaust. Great price and very fast delivery.
