    Review & Install Video

    So the Pypes Mid Muffler Cat-Back we're looking at today is for all 2011 through 2014 Mustang V6 owners. And it's gonna be a good option for someone that's looking for a big increase in volume out back while sticking to a tight budget. Now this will be one of the most affordable stainless steel cat-backs that offers a big boost in volume that's gonna be thanks to the straight-through M80 race mufflers. And like most if not all cat-backs or axle-backs, this isn't gonna take that much effort to get on. And you're looking at a straightforward one out of three wrenches on our difficulty meter here, about a two-hour job. And I will have more for you coming up on that later.So what you just heard in our sound clip is a strong four to five on the loud meter, so you're just shy of a really extreme set-up. Now with any exhaust out there, you can always go louder, but it's tough to get quieter. And what I really like about this is that it's a really great place to find that sweet spot or middle ground. So if you wanted to make the jump and go full core press, you can pick up a Pypes X-Pipe for just over $100, where you'd then be looking at a full five out of five. And that's still plenty more affordable than many other out-of-the-box exhausts with that level of volume. The system's pipes are primarily 409 stainless which is gonna help keep the price down. While they're not 304 stainless, they'll still hold up to rain and snow, but you might see some surface rust after a little while. Now keep in mind that it's something where no one's really gonna see this because it is gonna be under the car, and I wouldn't be too concerned about that. The 4-inch polished tips are made out of a 304 stainless, so they're always gonna be looking great. And moving forward or to the back, depending on how you're looking at it, we'll see the M80 mufflers used here are gonna be a 304 stainless steel as well. And they use a stainless steel mesh inside of a louvered tube that's packed with basalt insulation. Now basalt is said to manage sound better than a fiberglass, so you'll enjoy a deeper and more rich tone, which is gonna be important for the V6. So like I said earlier, this exhaust is one of the most affordable in the category. And at just around $500, you're getting a full stainless, a nice muffler, and plenty of volume with the ability to crank it up to a five out of five for just a few bucks more, and it's really a no-brainer. Now installation-wise, cat-backs go on with little to no effort at all, which makes them a great contender in my opinion. And you should expect a straightforward two hours' worth of wrenching, which is going to warrant an easy one out of three wrenches on our difficulty meter here.Now the tools required for the job will call for a pair of jack stands, a basic socket set, maybe some penetrating oil to hit your factory hangers. So you'll wanna start by getting your car's rear end off the ground. Then work with unbolting the existing system from directly behind your factory mid-pipe. So moving on, you'll get to the back of the car. Remove the axle-back portion of the system and then start back at the mid-pipe. Throw your mufflers in place, tighten down your intermediary piping, get your over axles in place, and then you're good to go.So that'll wrap up my quick review of Pypes Mid Muffler Cat-Back fitting the 2011 through 2014 V6. That can be found right here at AmericanMuscle.com.

    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!

        • 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.

            Awesome exhaust

            For being a lower end exhaust, this one is awesome. It was easy to install, used a rack, which only took about 45 minutes total including the stock exhaust. It has a much deeper tone than stock which is much better in my opinion. If you want an exhaust which gives you a good bang for you buck I recommend this exhaust system.

            Satisfying

            Everything 2k and up is so much more satisfying without adding too much drone when just cruising. Also doesn't idle crazy loud which is nice so I'm not waking up the neighbors. Going to be honest with the install time, took me about 4 hours. Mainly had trouble getting the stock exhaust out(getting both sides over the axle took about an hour) and had some trouble with the fitment on the drivers side when putting it on. Everything was done on jack stands and I could see this taking less than an hour on a lift. Also I'm totally new to all this.

            Deep rumble and pop perfect for a V6

            I have now had my pypes on for 2 weeks and I absolutely love the sound they put out. They have that deep growling sound to it the pops when you switch gears which sounds great. They're not too loud from the inside if you still want to listen to the radio and you're cruising at 80. I would definitely recommend them. They fit well with my cervini rear pipe body kit

            Great Sound!

            This setup has a great note to it - you wont have people accusing you of trying to emulate the sound of a V8, but it definitely has a deep, aggressive sound. Good idle volume, daily driving around town won't get you in trouble unless you put your foot down, then it reeeeeaaally screams!

            Mid muffler

            Three reason in giving it 3 starts instead of 5 is because the pipes weren't packaged good. When I received them they were bent on the opening and end of each one. I know that's not their for but if they would had put a little bit of extra protection I think it would had prevented it. Plus when I installed them the right pipe was laying against a metal and was producing a trumpet type of sound at first, so I had to do a little bit of mods to prevent it. Other than that the sound is good for a daily driver, and way better sound than the stock.

            Quality Product

            Could be a bit louder, but the exhaust note is great. The fit was pretty good up until the tips, which had a very hard time lining up with each other. For the quality at the price paid, I am stunned by what a great product this is.

            At first the exhaust was really loud but after they break in the mellow out on the inside and they are still super louder on the outside. This exhaust is great for cruising there is none what's so ever of exhaust drone but when you get into it a little you can hear it definitely

            Love how they sound

            Pondered on buying these catbacks for a while because when reading the reviews on them saw that they had a 50/50 chance of fitment being off but I took a leap of faith and bought them and I am glad I did. Didn't have no fitment problems whatsoever. I love how they sound. That rumble and deep grumble on the start up and idle and the crackle and pop when revving is absolutely amazing. Only problem I have with it is that around 4,000 rpm when accelerating the noise inside the cabin is loud and will sit there for a few seconds. I'm use to it now after hearing it so much. They are quiet though while you are idle or just simply cruising. Only time you hear them is when you have your foot on the gas. Different V8 owners stay telling me nice sounding GT I have and there faces be amazed when I say "oh it's only a V6".

            Great fit. Great look. Removing the stock axel over is tough without a lift. Install was easy. Sound with mid-pipe off and sounds with Pypes installed is very similar, so you get about as good of a sound as you can legally get.

            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!

            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.
