    Review & Install Video

    Hi everyone I’m Justin from AmericanMuscle.com, 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.

        5 Top Rated Questions

        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.

        Why are people having so many problems with fitment? Is there a quality control issue?

        • When it comes to Pypes, installation requires a bit more elbow grease than most other brands. It certainly should have any fitment issues in terms of not fitting, however it's not uncommon for a Pypes system to not fit like a glove, so to speak.

        will this Axel-back go well with an h-pipe or and off road h-pipe not really fan of the x-pipe sound so I'm just curious before purchasing

        • Yes, this axle-back will essentially work with any mid-pipe as it attaches to the intermediate/resonator pipes and not directly to the mid-pipe itself.

        Does it easily fit with MMD by FOOSE Rear Valance Diffuser? Or it requires its to fit it together

        • Yes, this Pypes Pype-Bomb Axle-Back Exhaust Will fit with the MMD by FOOSE Rear Valance Diffuser (item #387427) for 13-14 GT Mustangs.

        axleback resonator 1] Does the resonator reduce or increase the back pressure? 2] Is the increase in noise [loudness] just low or does it add rumble? Your video didn't really answer the question. 3] I assume the loudness passes noise ordinances? 4] How long would you expect the resonator to last before it gets too loud? I have the new 5 liter & would like to add some voice to it more like the newer Shelby units with some real rumble to it. 4 answers

            Love it!

            I was a little skeptical at first, but once I got it and installed it, it was a complete night and day difference from stock mufflers. No one would ever notice me driving my car until now! Everyone stops to look! Its hilarious! There is a but of drone on the highway but that is to be expected.

            Great product

            So I debated on what axle back I wanted and watched hundreds of reviews and sound clips. I finally settled on the Pype’s Pype Bomb. Easy to install. Great sound! Enough to scare my daughter! (She loves the car) and now she makes me ride with the windows down!

            Terrible fitment

            They sound great and I love the deep tone. Not raspy and annoying like most kits I’ve found. But. The fitment was horrible on my 2012. When using the hangers the muffler pipe and pipe on car were and inch off. When attaching to the pipe then putting the hangers on the mufflers went to the side and were touching the bumper. I had to cut off and reweld the hangers to get proper fitment. If you don’t mind the extra work they are worth it.

            Sounds amazing but ran into a problem

            The look and sound are great but I had to reinstall the axle back 2X trying to figure what it was. First try was the exhaust hanger was hitting the exhaust hanger bracket, that kinda helped but still hearing rattles so I took of the axle back all the way to the mid pipe where the h pipe is and reinstalled still some little rattle, as of that it sounds good but when you accelerate slowly you can hear the rattle from the trunk.

            Bad fitment on 2014 Mustang GT

            Installed these on my 2014 Mustang GT a week ago. When installing on the driver side i could already tell there was something off on the fitment as it was extremely difficult to get it bolted up. After installed, both sides were angling out to the side and touching the plastic rear bumper. Had to take to a local muffler shop and pay $80 for them to heat and bend the hangers so the mufflers could line up centered correctly. Very frustrating as i installed two other axleback systems on the same vehicle prior and everything lined up perfectly just didn't like the sound so went with Pypes. They sound good just disappointed i had to pay extra money to get fitment corrected due to Pypes not welding the hangers on in the correct spot.

            Very aggressive

            I have a resonator delete and these. Coming from Borla S-Types, they are far more aggressive and loud so keep that in mind. With my resonator delete, there was a lot of drone which is the only downside so I added some boommats to help. Would recommend for the price, they sound great! Install took about an hour and a half with a friend and some jack stands. Would HIGHLY recommend you get a friend help. Makes it a lot easier wiggling the exhausts in and out.

            Sound is Great, some annoyances.

            I really love the way they sound. I put them on my 2014 Mustang v6 and it made a huge difference. However, since I live in an apartment, I paid someone to do it. Like some other users, they fit horrendously when put on. The driver’s side was touching the bumper and made an awful rattling noise. I took my car back to the shop, and they cut and re-welded the hangers for them to fit better. They then welded the exhausts themselves in. They look much better. They do have a pretty bad drone for the first hundred miles or so (especially if you don’t tune it), but after they’re broken in, they sound amazing. Not quite a V8, but definitely more aggressive than a V6. Overall, I’m very pleased!

            2011 Mustang Cali Special

            These sound great, but the fitment is the worst. I would send them back but the local exhaust shop re-did the hangers and welded them so piping can fit and it still doesn’t. Drivers side sticks out a lot more then the passenger side. Wouldn’t buy pypes product unless there is an actual instal video made buy them. Not Happy with the exhaust leak I’m gonna have to deal with until I get another different set of axle-back.

            The only issue i had with these is the passenger side pype by the rear diff wasnt lining up right with the axle back. So i had to hold them in place while my friend welded them together. Other than the they sound pretty good. No drone

            Decent

            Sounds great, but the drivers side exhaust tip sticks out maybe an inch further then the passenger side. You notice it when you actually look at them. Took my car to an exhaust shop to see what they could do and said they'd have to cut it and reweld it. I paid around $300 for an exhaust. I am not paying to have someone cut and reweld them.
