Increase in Performance and Sound. Bolting on a Pypes Mid Muffler Cat-Back Exhaust to a stock 2011-2014 V6 Mustang will yield an instant 5 to 10 horsepower gain at the rear wheels. It features two of Pypes high flow M-80 Bullet Style Mufflers for the ultimate in unrestricted flow and power gains for a deeper throaty tone.

Aggressive Throaty Sound. The Pypes Mid Muffler Cat-Back features two high flow straight-through M-80 Bullet Mufflers that are mounted directly after the Mid Pipe, instead of after the axle, to produce an aggressive deep throaty muscle car tone with the help of two oversized stainless steel tips.

Quality Materials. This Pypes Mid Muffler Cat-Back Exhaust system is constructed from free flowing mandrel bent 2.5" 409 stainless steel tubing and features two Pypes M-80 Bullet straight-through mufflers for an aggressive throaty sound. The whole system is finished off with a set of 4" polished 304 stainless steel tips for modern Muscle Car styling.

Application. The Pypes Mid Muffler Cat-Back Exhaust kit is specifically designed to simply bolt-on to the existing factory hybrid H-Pipe of the 2011-2014 and newer 3.7L V6 Mustang for more power and a louder more aggressive sound.

Note. Stock 2011 V6 Mustangs come stock with a Mid Pipe that resembles both the H-Pipe and X-Pipe designs. This hybrid Mid Pipe was created by Ford to help add additional power and sound to the V6 straight out of the factory.

Will this fit into the BBK Catted X-Pipe with BBK long tube headers? If it doesn't fit into the BBK catted X-pipe, can you tell me which cat-backs will fit into it? or what I would need to make the cat back fit? Thanks!

JacobM

  • The Pypes Mid Muffler Cat-Back Exhaust will attach directly to the BBK Catted X-Pipe without any issues. The X pipe will also bolt to any catback exhaust designed to attach to an OEM X pipe, as the 2.75" BBK X pipe will neck down to 2.5" to connect to the OEM style catbacks.

Would this present any drone in my 2012 Automatic V6? Just curious as I am looking for a cat-back with no drone.

Colin

  • Hello! That's always a tough question because everyone always finds different sounds to be pleasing, however drone is mostly dependent on what speed you cruise at. Pypes exhaust system is on the more aggressive side for its sound, so I would say you will probably hear something while cruising.

    This sounds amazing. I was worried it would sound like a ricer but I was impressed. It has a low rumble but when you hit it, the car comes alive especially second gear. There is drone but I love it, it means I am heard and it puts a smile on my face. I never dread the day I put these on. If you want to be subtle and carry a conversation, you can, no problem but if you want to annoy your neighbors just give it a rev. It has small cackles in it but not overly loud. I definitely recommend these pipes especially paired with a cold air intake. It's a 10 out of 10 for me and worth the price.

    Go easy on the throttle and they are understated and refined but put your foot down and they get real mean real quick. The sound is deeper and way more aggressive than stock, but most importantly you feel a BIG difference in performance between these and stock. Install was too easy. Took me about 2 hours with simple hand tools. Highly recommend.

    No video will do it justice

    This exhaust sounds incredible! I never knew just how weak the factory exhaust sounded until I got these babies installed. Now my Mustang feels awake! It gets really loud in the cabin at 2750 RPM, but other than that is is just right. Sounds great in the low RPM range and howls when you floor it. If you lay off the gas a bit you can be as quiet as you want around town, but if you want to be noticed, that isn't a problem as well.

    Amazing

    Great product. Definitely woke up the car's exhaust note. Had a muffler shop install it for only 50 bucks. Looks great, sheds a few pounds, and sounds amazing. If you don't want to drop a grand on a catback exhaust system, this is the perfect way to go!

    Poor Fitment

    Non-stop rattling, the fitment is bad. It vibrates again the rear axles and bumper. My mechanic re-adjusted it multiple times and still rattling like crazy. Have to go to a muffler shop to get it re-shaped. If you have the money, get the others. Price reflects quality.

    So much better!

    This exhaust took roughly about 4 hours to install, with of course running into a few hiccups along the way. After putting this exhaust on it sounds amazing! It almost sounds as if it's running from the headers but in a very controlled way. It has a nice deep muscle car tone and screams when you get on it! After putting it on I noticed a burning smell then realized there's a coat of something on the exhaust system burning off which was normal. Overall, highly reccomend this exhaust if you're looking to give your V6 that means muscle car sound!

    Not too shabby

    I was a little worried about the volume and tone that would come along with doing a slightly less expensive set-up. The sound at idle is fantastic and aggressive. The tone between approximately 1500 rpm and 2800 rpm is okay, a little drone but not bad. The tone when you hit the powerband is beautiful, clear, throaty, and generally great. The volume is also a great compromise between loud and restrained. It is loud when you want, and perfectly quiet if you keep your foot out of it. So if your mustang is your daily like mine is, you don't have to worry about your neighbors hating you too much. The install time would be less than an hour if the mouth of one of the pipes hadn't been slightly bent. Its not hard to fix with a hammer and a dowel rod though. One piece of advice, make sure after install that none of the exhaust components are resting on or touching any part of the undercarriage. Otherwise you will hear it bounce and rattle on every bump, and it will rattle at idle. This happened to me even though everything was properly tightened with a torque wrench and looked to be in the right position. Always check your work!

    Great sound on pypes' catback exhaust.

    The sound is low and raspy on cold starts and when you floor it; especially in first and second. No drone at all and the sound is of excellent quality. I would recommend this catback to anyone wanting a throaty sound to their v-6. The one and only flaw is the hangers, they are not a perfect fit. I will upload pictures when i get it fixed.

    Perfect, Not too loud, Not too quiet

    Very good catback exhaust. The sound sounds great, not too loud but at the same time will turn some heads. Takes some time to get use to the new sound and smell but its worth it. I suggest getting it with a throttle body, new intake, and a bama tune. It will make you love your car again.

    Personally, Not A Fan

    As a preface, I have this exhaust with the bbk long tube headers and off-road x-pipe, so for stock applications, this review may not be as helpful. However, if you already possess these mods, you may look elsewhere. This catback does little to muffle and refine the sound of your engine. For a stock exhaust manifold, this is in theory a good thing, but for me, they came out obnoxiously loud and raspy. The V6 is already high-pitched and loud! At low rpm, it has a very nice, low rumble. Once you break 2800 rpm or so though, it screams and pops and generally offends people's ears. If you're into that, sure, but not for me personally. The fitment was great; the install didn't take too long at all with me and a friend, and the parts themselves didn't have any defects. I can't really complain about the part itself, it just didn't jive with my setup.

    Get what you pay for

    This exhaust system was a tough fit, and after spending more time adjusting the pipes than it took to install the system, I still have a rattle. I have tried adjusting it twice since installing it, but I have been unable to get rid of the rattle on the left side. As for sound, it does give you a deeper growl, but I feel it sounds more like an import exhaust sound then a muscle car sound. Overall it sounds better than stock and saves you some weight, but with the issues I have with the fit/rattle, I would go with a different system if I could exchange it.

    I Had a Roush system that had to be modified to sound better. but in the end i still hatted it for not being deep toned enough. This system on a V6 sounds awesome, I really like it much better. I would recommend this to anyone who wants to wake up that V6 engine. I will truly come alive.

    Great sound

    Could have been packaged better, but maybe that's delivery's fault, what's important is it was all there. Definitely jack/lift the car up as high as you can to make it easier to remove the mfg exhaust, otherwise you're fighting the angles to get the pipe out from under the car. Also a little tough to remove the factory axle back hangers from the factory mufflers, but nothing a flat screwdriver and some patient elbow grease can't handle. Pretty easy install of the new exhaust if you know which pipes go where, and the pipes that aren't universal are labeled L or R for the side they go on. Skip step 3 of the instructions until you get to Step 6. You can install the two rear axle back hangers, but don't reinstall the two front axle back hangers to the frame rail until after you've fit the muffler delete tailpipe (D) onto the over-the-axle portion of the midpipes (C). This way you easily slide the wire forms into the hangers and then bolt the hangers back onto the frame. Otherwise pretty easy, even for my first car project. Complete in under 4 hours by myself. If you're more experienced it'll be super easy. Absolutely great sound, not overly loud, just the right amount of meanness!

    Sounds like a V8

    This is a very loud exhaust. It sounds like a muscle car should. It made my V6 sound like a V8. I used a friends car lift and had the stock exhaust off and the new exhaust installed in almost exactly an hour. There were several mechanics around that asked me if it was a V8. They all thought it sounded as amazing as I did. The materials are very high quality. If you examine all of the parts you'll see that it's almost completely straight pipes. The "muffler" is more of a resonator than anything. If you want to know how loud it is, just unbolt your exhaust behind the cats. That's what you'll be working with. We only had one small issue getting them lined up symmetrically. The left side hangers were bent a little different from the right. It took a bit of muscle to bend the hangers so they matched. The tips stick out pretty far beyond the bumper but you can pound them in with a mallet as far back as you want. Overall I am very pleased with this exhaust.

    Great but flawed

    Love the sound of this system. However installation was a pain due to one of the mid pipes being slightly flattened on the rearward end. Barely visible to the eye, but required a lot of elbow grease to get it to connect to the axle back portion. Some quality control please Pypes!
