Description
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.

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 ...

Will this work with BBK longtube headers? Have a 2012 v6, am wondering if this mid muffler system will work with the BBK longtube headers.

  • You will still need the BBK X pipe designed for long tube headers.

Mid-Pipe fitment? If I install BBK long tubes and Shorty O/R X-pipe, will this catback attach directly to my X-pipe or do I need any welding/cutting?

bige930

  • Everything should be a straight forward bolt-up design, so no, no welding or cutting required.

    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.

    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.

    007 of catebacks

    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!

    So I was skeptical at first but this is great product hands down. It was a quick install and fairly easy. I recommend it for all v6 owners looking for aggression.

    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!

    Amazing sound

    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.
