Application. This MAC Performance Pro Chamber Off-road Mid-pipe is designed as a direct bolt-on for the 2011-2014 3.7L V6 Mustangs with either aftermarket short tube headers or the factory manifolds installed. Intended for off-road, track use only, does not include catalytic converters.

Please 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. This MAC aftermarket Mid Pipe will further help you reach maximum air-flow equaling additional power.

I have a 14 mustang automatic I am looking for a more deep sound without rasp, I have the touring axle backs on it now and want to add bbk shortys and this h pipe, will this make it less loud then the s type borla or louder? Also will I need anything else if I ordered these with my tourings I have now

TylerR

Assuming I have a bone stock '13 3.7, what will be the difference in terms of volume and tone between adding an H-Pipe or the MAC Pro Chamber Pipe?

CamaroLOL

  • The pro-chamber is basically an H-pipe on steroids. So an H-pipe is designed to bring the tone to a bit of a deeper sound, and because of this it's a bit quieter than an X-pipe. So with that being said, the pro chamber will be even deeper and slightly quieter still relative to an H-pipe.

Hi AM, What exactly is the difference between Pro Chamber and an H-Pipe? Thanks.

CamaroLOL

  • The difference is that the H-pipe connects the right and left exhaust pipes with a single pipe. The Pro Chamber connects it with an actual chamber that will not only increase the after header sound but will increase the amount of flow to exit.

Hi AM, I have a 2013 V6 with Roush ABs CAI, along with BBK Shorties. To keep the car legal, I plan to add Pypes High Flow Metallic Cats with this mid-pipe. Am I able to do that? Will this mid pipe bolt right up onto my BBK shorties? What changes will I notice in terms of volume and tone? Thanks!

CamaroLOL

  • We highly recommend staying with the same brand of mid-pipe as the headers due to differences in manufacturing tolerances which may skew installation. Using this MAC Off-Road Pro Chamber Mid Pipe will bolt up to stock and most aftermarket shorty headers, but again due to tolerances in manufacturing exhaust alignment may be skewed. Adding catalytic converters will help pass inspection in most states, however, we would recommend speaking with your local official inspection station for exact state specifications. The exhaust is slightly larger, so you will be able to flow more volume while producing a more aggressive muscle car rumble to the sound of your exhaust.

How raspy is this mid pipe?

Alex

  • This mid pipe is going to be a little bit on the raspy side, but it will not be anything to out of hand. It will also depend on what other exhaust components you are pairing this with. Different mufflers can drastically change the sound.

Do i neec to buy anything else with these?

John

  • Not necessarily. In terms of install and functionality nothing else is needed, however since this product is deleting your catalytic converters, you're going to have a pesky check-engine light pop up. This can be turned off with any form of custom tune and if you don't have a tuner you can, for example, purchase our BAMA tuner to achieve this as well.

    Part 2 Review

    To begin with, your cold starts will have a some amount of rasp with some hints of deep rumble here and there as the revolutions begin to drop but they will be very loud and who doesn't love an extra loud cold start. Second, at idle, it is louder but it comes with the price of the gassy smell. Simply rolling up your windows will fix that for you. When rolling, you won't smell it if you have the windows down. Please be advised, if you have an O/R pipe and your car is a daily, because of the volume of the pipe, having a conversation inside won't be so pleasant. Third, as I said in my previous review, there is plenty of rasp throughout the powerband HOWEVER, you'll learn to manage it by shifting at certain points with a combination of how heavily you put your foot on the gas. For example, I learned to cruise in the city (NYC) at no more than 30 throttle and I must shift before 2,900. If I want to shift pass pass that, I need to get to a 50 throttle between 3,000-3,100RPMs (that's where it gets annoyingly raspy) and if I maintain that 50 after 2,900 it is no longer raspy but the deep rumble begins to faintly disappear. Cruising through the city managing the rasp very well will result in breaking necks and a smile on your face. Please keep in mind, this is a V6, not a V8, so there will be times where the rasp will come out and you won't be able to do anything about it. That's something that I've learned to accept and you will have to too if you get this pipe. Fourth, a personal experience of mine, when I take off normally from a green light and the following light is still red AND I maintain at 1st gear, when letting the gas go and it drops in RPMs, this beast ROARS from 3,000-2,000. This is something that I absolutely love and can't deny it. This will feed your Mustang pride and will make you feel powerful, especially around Hemis', SRTs, SSs, Ms, and AMGs. Fifth, this mid pipe REQUIRES some amount of time to break in before the raspiness begins to fade away. I had this O/R set up for 3 months and the rasp was still there HOWEVER, it has some minimal deep tone to it. The best way to break it in quicker is to drive (I recommend highways at night) at high RPMs and endure that painful rasp. Practicing your 0-60s also do the trick. Sixth, THE VOLUME IS THERE. Before, I had Roush ABs, CAI, and BBK Shorties. On a volume scale of 1-10, assuming 5 is bone stock and 7 my previous set up, adding this pipe will sit you at around a 9. If you currently have muffler and/or resonator deletes, it will be more than what you bargained for, especially for a V6. Finally, I STRONGLY RECOMMEND buying the cats offered here for 11-14 models when purchasing this pipe. Install both at the same time. THE PYPES CATS HELP ELIMINATE 85 OF RASP, PLUS DEEPENING THE TONE, ALMOST LIKE AN ARTIFICIAL 5.0 (Please refer to that product to read my review there!) As for power gains, this pipe had to be installed with a tuner, so, yes, I can definitely feel the change but that doesn't necessarily mean the car now has 300RWHP. What I can share with you guys is that my 0-60 dropped from 6.4 to 6.2 on 87OCT so that's good. Also, that the 1st and 2nd gear are a whole new thing when I step on it. The pedal is very sensitive w/ a tune especially with 93OCT. I had to keep it on 87 for NYC. The car does sound throatier but no, the tuner did not do that. That crossover design it what helps produce it. With my setup, I think I could be sitting between 275-285RWHP. I've been told by some AM staff that the BBK Throttle Body COULD possibly tone the rasp, along the Pypes cats I mentioned earlier. In the end, I give this product and AM a solid 3 stars because if you're not a fan of rasp, you'll end up spending another $300 for a set of cats labor OR $ 4xx.xx for new axle backs or catbacks. Because it's an off-road and AM did not bother to do the effort to also add a catted version, you'll HAVE TO spend an extra $400 for a Tuner. This $475 ended up costing me almost $1,200.

    Part 1 Review

    This is the same guy who gave this pipe 2 stars earlier and it's only fair to MAC, AM, and the rest of you guys that I also share my COMPLETE HONEST OPINION after having this product installed during my Off-Road period. For this section, I'll share my opinion based off how AM marketed this mid pipe. Increased Exhaust Flow: Absolutely. I love loud but I personally think it's a little too loud for NYC. A noticeable volume increase especially if you have swapped your mufflers out for aftermarket ones. Aggressive Muscle Car Rumble: Yes, BUT it does come with a price of lots of rasp. I will dive into detail with this in Part 2 of this review. High Quality Construction: AM Staff has yet to confirm the steel grade on this mid pipe. Though it says "Stainless Steel", that it still doesn't confirm the grade on it. My educational guess is that this MAY be a 409-grade. Why? Because my BBK Shorties are 304s and when I took them out of the box, they were clean and shiny and after 8 months installed, they still have a dull grey color and the funny thing is that they're not ceramic. When I took the mid-pipe out of the box, it smelled like dirty steel, it was greasy and dusty. I would hate to think that AM is charging almost $500 for Aluminized Steel. Application: There was a fitment problem with the stock Over-Axle Backs. They were the same diameter so the mechanic had to expand the diameter tubing on the mid pipe. As for the other end, this MAC hooked onto the BBKs just fine. In the end, AM should either carry more H-pipes for the V6 or simply be more detailed about this product. Upload a video, HP gains, be honest about the product, etc.

    Raspy after 2,500

    I had a 2013 with Roush ABs, CAI, and BBK Shorties and it sounded like perfect artificial 5.0. Simply, I was looking for more volume. The mid pipe itself is average. If you're looking for stupid loud with lots a rasp, this is it. I live in NYC and I can't even go pass 3,000 because it's just pure rasp. There is no "Agressive Muscle Car Rumble" pass 2,500. In my opinion, if you want to keep your throaty tone and moderately volumed V6 and is looking to increase both, don't buy this and look into some high-flow cats and/or resonators from your local shop to install onto the stock pipe. My guy charged me 90 and took into the stock pipe for 70. I hope he still has it because I'm planning to go back.

    BEASTLY!

    Prior to install, the sound on my 2012 V6 Premium Mustang with an Airaid Cold air intake, bama tune, and Borla ATAK Exhaust was decent. It had a loud high note when you laid on it but not very deep. With this install I was mainly looking for a deeper sound, and boy did I get it and more! This Mid-Pipe is crazy, my mustang sounds like an entirely different mustang! If you have a Borla ATAK Exhaust on, it is going to be at least twice as loud with this pipe when you get over 3-4k RPMs! It has a very loud bark, and sounds brutal when you lay on it. With my setup I do notice drone over 2k when im on the highway though. Its a manageable drone, but fair warning there is definitely some. My favorite part about the mid pipe is the deepness to the growl while it idles. Much lower note, and was exactly what I wanted in that regard! If your looking for a head turning part, that will really wake up your mustang this is definitely the one! I was told by others to get an X-Pipe but I was very glad I didn't because this midpipe does more than plenty!

    Mac off road pro chamber

    This mid pipe is quite the beast. It comes all shined up in the box. Weighs 23 pounds. Install took less than 4 hours with 2 people and about 1 1/2 foot of extensions. The box hangs down about 2 inches lower so watch out for speed bumps and driveways. Now for the tone. I have flowmaster 40 series welded in for my axlebacks, which are already raspy. If you putt putt around town under 2500 rpm it sounds the same as if you had cats. If you get on it, it'll wail. A lot of off road pipes have a harsh rasp at 3000 rpm. As does this one, yet, it's not as bad. It's deeper, has more bass, and more power than the H. I highly recommend this mid pipe because it still sounds like a stock setup until under heavy throttle. Very sleeper like. The bass on startup will shake your chest.
