      Review & Installation Video

      The Pypes Pype-Bomb axle-back system we're taking a quick look at today is going to be a good option for any 2011 through 2014 V6 owner out there that's going to be on a budget, but for someone that's going to be looking to make some serious noise outside and inside the cabin. Any axle-back for this platform can get thrown on with little to no effort at all. For that, it's going to be catching a very easy one out of three wrenches on our difficulty meter here, about 30 minute to an hour's worth of labor. We're going to show you how coming up real soon. What you just heard does not do this system justice. This is easily getting a four out of five on the loudness or the Wake the Neighbors, or Wake the Dead scale here, and it's easy to see why. Now, this straight-through muffler delete is going to be ditching your factory-style chambered mufflers, and it's going to provide a very loud and aggressive tone, and one that one of our customers back on the product page described as "ripping a hole in the ozone." Now, with that said, this system is absolutely going to turn heads, whether you like it or not. It is going to be manageable, but that's going to be dependent upon how far your sticking your foot to the floor. Now, it goes without saying here, guys, customers looking for this system should be expecting one of the loudest systems that you can put on your 3.7 right now. However, if you're the one customer out there, kind of like myself, that wants to go as loud as possible, there's absolutely no reason why you couldn't throw an off-road X-pipe onto this. But expect that to be incredibly loud. Now, aside from plenty of noise, you're going to be looking at some of the best material as possible for an exhaust. That's going to be 304 stainless, which is going to be optimal compared to 409, because it is going to resist rust that much better. Now, this is going to feature two and a half-inch mandrel-bent tubing that's going to feed through their four-inch resonated tips. I don't want to confuse anybody here. Pypes states that this is going to eliminate lots of feedback, like snap, crackle, and pops. My personal experience with this system, you should expect to have a lot of noise coming out of the back of your car. Muffler delete systems are going to be inherently louder, because you're not going to have anything coming out of the tips right here. This is going to be very straight through. Now, with that lack of materials here, it's going to directly affect the price. For that, we're going to see this land right around the $290 to $310 range. Installation-wise, axle-backs go on with little to no effort at all. Again, this is going to warrant a very easy one out of three wrenches on our difficulty meter here, about 30 minutes to an hour's worth of labor with basic hand tools. Aside from a basic socket set, a jack and a pair of jack stands, and maybe a little bit of penetrating oil to hit your exhaust hangers or isolators are all that you're going to need here. Once your rear end is up off the ground, it's merely just going to be unbolting all your hangers and your factory system, removing it out of the car, getting your new Pypes system in place, and utilizing your factory hangers and isolators. Bolting everything down, making sure your tips are aligned, you're good to go. So that's going to do it for my quick review of Pypes Pype-Bomb axle-back system, fitting your 2011 through 2014 V6 Mustang, that can be found right here at

        Good for some

        Ran at first with stock catted x pipe, sounded great, Higher pitched than other options but ran great. Put on a Lethal off-road h pipe and the idle is great, but under accel and high rpms it sounds a little rough around the edges

        Not bad satisfied overall

        Sounds great, it really isnt as loud as some say. My only problem is that the long hanger near the tip is to long, it allows the pipe to rube on the outer side of the bumper causing vibrations and paint wear. just going to find some clasps to shorten the hanger for alignment.

        Sounds Great!

        2014 V6 w/ Spectre CAI, BBK 73mm TB, E3 Spark Plugs, BBK Shorty Headers, and now Pypes Pype Bomb axle back. This set up sounds great and looks great! Start up sounds amazing. It has a low deep rumble at idle and at low RPM. At 2nd gear and up it has a deep rasp, not ricey at all. NO drone. After installation I immediately felt a bump in HP and torque, thanks to its free flowing design. My only issue is with hanger location on both resonators. I had to re position the set up 3 times because i had to pull the mod pipe down a couple inches. This made it consistently tap on the pan hard bar support brace. Which gets annoying. If you buy this set up, do it the right way with no short cuts. Loosen all bolts on the mid pipe and remove the hanger brackets. Its extra work but will make fitment easier. It really only spent an hour to install. Overall, good bang for your buck.

        Good sound, tough fitment.

        I was very hesitant to buy these, and was considering the Borla atak. I decided after many days of consideration to give the pypes a try, and I do not regret it. They are extremely loud for the first 100-150 miles or so, but get much quieter after that. I'd say a 4/5 loudness at first then a 2.5-3/5 after some miles. They have a nice deep tone in the low end and a raspy tone in the high revs. They have a lot of interior drone at 2k rpm. They pop and crackly when you rev, and I love it! Mine, along with many others, had fitment issues on one side. You have to loosen your xpipe to get them to align. If you take it to a shop, let them know about the possible fitment situation prior to install. I'd say if you're on a budget, go for it! I love mine and cant wait to get headers.

        Loud and proud!

        An excellent, budget friendly to make any v6 rumble without the rasp! Only complaint would be the driver side pipes geometry was a bit off so it didn't wan't to clamp properly at first even when unbolting the midpipe. Other than that excellent exaust.

      • 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.

      Is is safe for the engine? Because someone told me that when you take the maffler out, and instale just pipes, the pressure will change and it might burn the valves? Also do I need to program the car?

      • A complete loss of exhaust back pressure could cause damage to the valves, however, simply installing an axle back would not cause conditions that could damage the valves. Also, if you still have catalytic converters installed, those will give you back pressure. So yes, this safe for the engine, and no, you would not need a tune to install these.

      What is better an X pipe or a H pipe for sound with this exhaust?

      • An X pipe will give you a higher pitch and raspy tone. The H pipe will offer a deeper muscle car tone.

      I saw you guys said it wasn’t going to pass the sound legal level in CA but how off is it 96, 97? Any other options that would be legal for CA sound level ?

      • Unfortunately with the new exhaust law passed in California. We would be unable to guarantee that any of the exhausts offered will pass. We recommend checking with your state ordinances or a local shop.
