      Review & Installation Video

      Hey everyone I’m Justin with and I’m taking a look at Pypes black pype-bomb axle back exhaust system for your 2011 and up Mustang GT. The pype bomb is for someone who wants to be both seen, and heard, this is due to the fact that this kit uses muffler deleting, resonator tips, which allow for a much more aggressive exhaust note. The system is constructed from free flowing, mandrel bent, 304 stainless and features two 4 inch resonator tips with a black powdercoated finish. Install is very easy and should take you about an hour using standard hand tools. Let’s hear how to pype bombs compare to the factory exhaust.

        I have been trying to find the pipes I wanted to get the sound I wanted and found these. After two years of searching and I love the look and the sound. They are a bit loud but the local police have not stopped me even when one was following me.

        Not as bad as everyone says.

        Alright let's start with the Shipping, shipping was incredibly fast, like I'm talking about I bought it late night and in the morning it was already shipped so that's awesome! Next let's talk packaging, each muffler is sitting opposite to each other in the box wrapped and foam on the tips and bubble wrap, still somehow the tips ended up dinged, so I honestly think that these get dinged at the factory before it gets packaged because how mine was packaged there was just no way it could get damaged during transit. Now let's talk about supplied part and the fit. First off if I could give one large piece of advice to Pypes it would be this, I'd honestly pay a little more if they came with a pair of exhaust clamps, I personally hated that I had to cut mine off to be reused, but I also understand that this is a budget axel back so I didn't dwell on it too much. Now for the fit, as for the length sticking out of the bumper, this axel back sticks out quite a bit compared to other axel backs and this has to be done by design and honestly I love that look and is 70 of the reason I got it. When bolted on correctly mine say spread out, meaning looking from the back of the car the left muffler sits alot closer to the left leaving a gap to the right of the muffler. The passenger side muffler sat exactly like the left however mirrored so it sat closer to the right leaving a gap to the left. They basically hug the bumper very tightly. To get them to fit in the center how I liked all I did was unbolt the exhaust clamps hold them in the position I wanted mark them with a marker and wrapped the marked point in plasma tape, and in a couple of weeks I'm heading to a buddies shop to weld a small rim where the tape is in order for the rubber hanger to not move around keeping it centered. Lastly let's talk about sound, well good news is they sound great, they're a hair quieter thank having no mufflers at all, but it's noticably deeper in tone, okay now for the big one DRONE, does it have drone? Of course it does again referencing to having no mufflers at all you have a large "cone" of drone from 2000-3000rpm. With this axel back it tightens that cone to 1900-2100rpm, and admittedly it gets pretty rough at that rpm. For the conclusion this is definitely a budget system, but does that mean it's a bad system? Absolutely not, truth be told I think this system is incredible for the price, there can definitely be improvements to make this better and that's reflected in the 4/5 star rating I'm giving this. So if you're looking for a nice budget system that'll have some real killer presentation I couldn't argue with anyone if they brought up this system into the argument.

        Sound great!

        The fit was only tricky in that the factory interface is a ball-style flange, which doesn't orient itself. With some effort, you can get it to seal, but it's not "plug-n-play". My factory pipes were rusted on, but the Mustang's scissor-jack, between the traction-bar and the muffler end, popped them right off.

        Great Exhaust

        Great product, fitment was perfect, was worried this exhaust would be too loud because it is a muffler delete, but the 4 inch resonated tips do a great job of keeping the volume down. Great deep tone, also nice crackle when down shifting.

      5 Top Rated Questions

      Which one has the deepest sound? Pype-Bomb, SLP Loud Mouth, or MBRP Muffler Delete?

      The description says that the resonator tips eliminate the popping sound. If I put these on my Boss 302 will I still get that popping sound due to the side exit exhausts?

      • This would not eliminate exhaust popping no.

      I accidentally ordered these instead of the v6 option,would these fit the v6 or is there a big difference to where it would definitely not fit.

      • The Pypes Black Pype-Bomb Axle-Back Exhaust is designed to fit the the 2011 to 2014 GT Mustangs, It may fit the V6 however it has not been tested so we can not guarantee the fitment due to piping size.

      Does this system cause any drone?

      • The Pypes Black Pype-Bomb Axle-Back Exhaust (11-14 GT) will have some drone. The only exhaust company's we carry that offer zero drone would be Corsa and Roush exhaust.

      I have the Borla ATAK catback system and am looking for a louder muffler. I had Pypes on my 2010 and loved the sound. I'm just curious if I'd be able to mount these mufflers to the Borla catback system that I currently have installed. It's 2.75" and I don't think these 3" mufflers would mount right. Any suggestions? 1 answer
      pypes axle back or pypes cat back I have a stock 2013 GT. I am going to buy a CAI/tuner combo (still deciding) and I want to change the exhaust. I am looking at this and the Pypes catback super system. Does the catback do much for power? It doesnt seem like the axle back does anything for power. I do love the black exhaust though. If the horsepower increase is minimal I may go with the axle back for looks of black but if I can get 20hp then maybe it is worth it. Lots here but hope someone can help me out. 1 answer
