      Review & Installation 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 Exhaust Note
      • Resonator Tips
      • Polished 304 Stainless Steel Construction
      • Fits 2011-2014 GT Mustangs


      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.

        Axle back

        These pipes sound great! Got a set on my 2005 GT and now a set on my 2011 GT, it's a great way for the neighbors to know when you're leaving or getting home. Excellent sound and made from stainless steel so they last forever.

        Came with the car

        So honestly wish they had given these a noise rating to compare with something like roush or the corsa or even the outlaws there not that loud and the tone is just not a good tone the 5.0 is capable of so much better the only part of this system that’s loud is the DRONE do not recommend

        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!

        2 2012 GT - CurtisP Installation Time: Afternoon

        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.

        5 2014 GT - Gemar Installation Time: Afternoon

        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.

      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
      Pypes for V6? I have a V6 with Performance Pack and would really like to get a set of Pypes for it. Will these fit the 2012 V6? I've seen other sites that list the Pypes for the V6 but would rather give my business to AM if possible. 2 answers
