Description
More Horsepower And Torque. Replace those restrictive factory manifolds with a set of MAC Shorty Headers to improve your Mustangs exhaust flow and increase your horsepower and torque throughout the entire RPM band.

Ceramic Coating. These Shorty Headers are completed in MAC's Polished Ceramic Coating that not only looks great, but reduce under hood temperatures to help increase horsepower and extend the life of the headers. Ceramic Coated headers will long out last both chrome plated and polished headers.

High Quality Construction. Constructed from 1-5/8" mandrel bent 16 gauge steel tubing so there are no kinks to rob you of power, these MAC Performance Headers feature 2-1/2" True Fit Collectors that eliminate the need for gaskets which are prone to leak and blow out. These headers are then completed in a polished ceramic finish for good looks and a durable long life.

Application. Designed as a direct bolt on, these MAC Shorty Headers will bolt straight up in the stock location to the factory Mid-Pipe on both automatic and manual 2011 to 2014 3.7L V6 Mustangs to improve exhaust flow and sound. Technical Note. This MAC Performance product is not legal for use in emission restrictive states.

I just bought my 14' v6 last month and am making a wish list... I wanted to know are these a direct fit with the catalytic converters and O2 system?

  • Yes. They are a direct bolt on replacement. Think about buying a tuner if you want to maximize performance and gas mileage. You can't beat free tunes for life!

I just installed a K N intake with a 73mm throttle body and a spacer on my 2014 V6 convertible. Runs great. It is my everyday driver and I drive about 25,000. I love great performance and want the added power and could use some additional sound. I like the headers for the power and look. Since I don't want a lot of extra sound (Nothing LOUD or RASPY.) would it be ok to hook them up to my stock exhaust? Would I get some sound and better performance or should I add additional exhaust components?

how much hp & torque do you get from this mod alone? Would you say this is better than the ceramic bbk Shorty headers? Trying to decide which one I should get and gains and sound.

bobbyyliight

  • They may be rated for +10HP but the biggest change/gain you will notice is in the sound. It will really open up your exhaust and let it breath. You will love the sound !!

    Decided to be the Guinea Pig on these

    I bought these without any prior reviews because of an overwhelming forum response that MAC was the better company over BBK. Also because I thought the radical tubing design would look cooler under the hood. So far, I'm very happy with them. The welds are fantastic and the product is made very well. Fitment is perfect. I was a little upset to see they didn't come with gaskets, but reusing the stock ones proved to work just fine. I can't comment on the sound or the installation time as I installed these at the same time as my Lethal Performance H-Pipe and welded on glasspacks almost immediately, but the combination of the 3 with my Pype Bombs sounds FANTASTIC. If I had to do it again, I'd still take these over the BBK. And a word of advice: Because of the tubing, you will need a combo wrench for most of the bolts. A gearwrench will save you a ton of frustration. The stock manifolds are 13mm, the bolts that come with these are 12mm. Here's a video: https://www.youtube.com/watch?v=MFUJzACASZQ

    Awesome Mac headers

    Smooth sound and acceleration with these new headers. The motor runs so much more free. I have a V6 Roush with Cat back exhaust. Improved the sound greatly with no back fire sound. Use a couple factor studs to align the headers during install. Then replace with bolts one at a time. So much easier. Really like the look as well. Glad I bought and wish I bought sooner.

    LOOK GREAT! SOUND GREAT!!

    These headers are all you can ask for. They deepened the exhaust note slightly and paired with ROUSH axlebacks they sound amazing. There seems to be a more free flowing sound to the exhaust. Not as many pops and gargles that come when you let off the gas with the axlebacks. There is a noticeable gain of torque and response throughout the whole range, mostly noticed in second and third. My only regret is not getting them sooner! Thanks AM staff for wicked fast shipping and exceptional support! Get the headers if your on the fence, you wont be disappointed! Oh, And I am loving the fresh new look of the ceramic coating each time I open the hood! Worth the extra bucks if you are planning on keeping the car for a long time, and even if your not, youd be doing someone else a favor!

    Awesome set!

    Okay few things to answer possible questions. -get the stock headers off was no problem just spray with Gibbs -the shop was only needed because I have lethal performance h pipe and the flange was different not a big deal and not AM's fault at all! -I kept the stock gaskets (even though Mac uses true connectors I just like a piece of mind) plus the gaskets were perfectly fine even after 50k miles. -one downside but easily fixed was the driver side manifold flange rubs the steering column so just zip a bit of it off with a sawzall and you'll be right as rain! On the review itself I believe these a very good part because of the equal length pipes! Very good sound deep and rumbly as a v6 can be haha! Definitely feel the power added and pulls a lot harder.

    MAC CERAMIC SHORTY HEADERS (11-14 V6)

    Took a while to get, but the headers did arrive in good condition. When doing this, remember to get a new exhaust gasket. The work took me about a day. Removal of the old manifold was quick and easy. Having the right tools helped. Installed the drivers side 1st, pretty straight forward. However on the passenger side I did have a fitment issue. The bolt holes on the collector did not line up. It took a couple hours of work to get that side mated and sealed. I have been driving it for a couple months now. Sounds good, a little deeper rumble. I've noticed modest performance gains with low end torque and throttle response. Also added a throttle body. Need to do a tune to really get the most out of it.

    Noticeable power difference.

    Well I had procrastinating for awhile on these headers. Once I received them I noticed how well constructed they had been made. I cannot emphasize more on how much more fun it is after getting these installed. The oem headers btw are so much smaller and you realize how much restriction they had on the performance. Awesome gain through the entire power band. Highly recommended these for the other fellow PONY owners out there.

    Not bad for an afternoon install

    Installation was pretty straight forward. I took the battery box and battery out for the right side install, which made things so much easier. Overall about a three hour project. Really like the sound, I already have Borla axle backs on the car. Don't have any documented performance data but my seat of the pants impression is this mod increased my low end power considerably.

    Amazing increase in power and torque.

    I bought the MAC shorty headers for my 2013 V6 convertible several months ago and waited until I could afford to have them installed by the Ford dealer last week. It took the Ford tech about 4 hours to install. The change in performance is hard to describe without superlatives. The power used to come in around 4000 RPM. Now it starts around 2000 RPM. Where the car used to just chirp when I shifted into second, now with these MAC headers it starts to fishtail like a 5.0": I was not expecting that kind of improvement. Had I known how much more power this made I would have done it as soon as I took delivery of the car. The car does have a BAMA 91 octane tune, a 73mm BBK Throttle Body, a K&N drop-in air filter, a Steeda shifter bushing, and a "Driveshaft Shop" carbon fiber driveshaft. I am guessing that the V6 may now be pushing 350hp and getting close to 300 ft/lbs of torque (at the rear wheels), but I have not had it dyno'd yet. Just get these headers ...and btw the AM techs told me it does not need a tune for these shorty headers. What is not to like?

    Good sound and flow

    Noticable difference in sound and air flow. Had fitment issues on one side. Had to take it to a shop to get adjusted to fit.
