  • Mid Muffler Design
  • 2.5" 409 Stainless Steel Tubing

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.

Do the cats stay on?? I don't want my car to go out of warranty by taking the cats off so wondering if they stay on with this?

Any videos or sound clips to help me make a decision?

Chris

  • Unfortunately we do not have any sound clips of the Pypes Mid Muffler Cat-Back Exhaust. I have personally heard this kit and I think it has a nice deep smoother tone to it. I also enjoy the look of not having any mufflers hiding behind your exhaust tips, makes it look like a nice clean setup!

    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.

    Beautiful sounding

    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.

    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!

    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.

    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!

    Ok to start off i have been looking for an exhaust that i can put on my mustang that wont make it sound like a ricer! and hearing it myself and doing a lot of hw i have to say that this is the meanest sounding exhaust you can buy for the V6! absolutly love it. i havent checked the hp gains but i can feel the improvement. I highly recomend this product. it took me 22 and my brother 16 about 3 hours to put on. but i will get it welded soon i dont trust the brackets it came with.

    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.

    LOUD

    This exhaust is very very loud (granted I have Long tube headers and catted x-pipe) definitely not for someone that doesn't enjoy loud, sometimes overly obnoxious sound. Over this is an amazing exhaust. At idle its quiet at cruising speeds you barely notice it, but at WOT it screams. At the price you cant beat it.

    Juiced UP

    if you really want your stang to sound and feel like the real deal you cant go wrong with this setup. I started with a steeda CAI, BBK long tube headers, shorty catted x-pipe, and finished with the pypes catback along with a BAMA custom tune. My car sounds sweeter than i imagined and the power is amazing. being that the mufflers are basically straight through it is extremely loud if you get on it, but with the modifications i listed it now has the distinctive rich girgling sound of a true mustang when cruising and under acceleration. My only dilemna...the new pipes connecting the catback exhaust were much bigger in diameter than the BBK x-pipe and therefore would not properly connect together. I wound up temporarily wrapping the connecting ends of the x-pipe with a cloth just to make them big enough for the clamp to secure in place until i got it welded the next day. nothing a little tweaking can't handle. i know it may sound a little inconvenient if you do it yourself but it took me about 5 hours. i definitely recommend this exhaust system to anyone who wants to add RAW SOUND and TRUE POWER gains hands down! if you don't have a lift, be prepared to cut the stock midpipe or have a local shop install.

    A lot of BANG for your buck.

    It is loud, deeper than all of axelbacks I have compared it to in person. Excited to add an xpipe to it for a much stronger and raspier sound.

    Amazing sound!

    I have had it for about two weeks now with BBK o/r X-pipe and BBK Long tubes. It has the loud crackle at 3K RPM. besides that it is a low muscle car rumble. Very loud when on the gas. Hangers suck though. Rattled a bit vibrating against the car. The shop had to bend one of the hangers to stop it. But for the price and sound it's amazing!

    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.

    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.
