Description
More Horsepower And Torque. Replace those restrictive stock 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.

  • 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 !!

Answer This Question

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?

    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

    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.
