  MAC Shortys

  Headers work well. Really got extra power by replacing entire exhaust system with 2.5" pipes all the way from headers to mufflers. Fit was not so good. The flange to the cat back pipes interfered with the steering column on the drivers side. Had to be cut back to clear. This of course caused extra cost for the install. Other than that I am quite satisfied as I have achieved the extra power I was looking for.

  No Quality Control

  I received this product and the only thing that had been done were tack welds. The product was leaking from every connection. It was impossible to get in touch with MAC customer service. So thankful I bought it from AM, whom provided excellent customer service in facilitating my return. Never again.

  Mac Headers

  No installation instructions or guidelines, didn't come with gaskets and after all that they didn't come close to fitting. The collector flange on the driver side hit the steering shaft, the cone on the passenger side was way off, wouldn't bolt up, had to remove and install stock manifolds back on and return for another brand.

  Better then longtubes (sound)

  My mustang is highly modified, this was the 2nd last mod of mine until I either boost or stoke out my engine..the car purs at idle, barley any louder, once given just a bit of throttle though and the car wakes up to a roar! Their is an increase in power, especially with a tune, it's greatest benefit seems to be the smooth transitions in the powerband..No longer the car jerks it very smooth and elegantly goes from tame to CRAZY in both sound and power. I highly recommend a shop for this particular Shorty..I had to get my catback exhaust slightly modified to be able to fit these headers, they don't line up correctly.

  Great if they fit!

  Alright, so I bought these headers as I finally bit the bullet. I was excited, and went with the ceramics so they wouldn't rust. Day one: got them installed in about 4 hrs. Huge exhaust leak on start up with stock gaskets. After about a week, I received my new gaskets in the mail and ripped everything off, did them again about 30 minutes faster. Then, on start up, the same exact leak was back again. Ended up costing me $75 to get the leak fixed. Shop owner said, the headers were tweaked from factory and came up with some custom fabrication. I've had these headers for more than 6 months now, they looked better when I first had them because they do infact slightly rust. Though, after everything, they do look good, and sound awesome. Would I do it again, no, but glad I have them.

  It doesn't fit the angle.

  The one on the right doesn't fit the angle perfectly, which makes the sound horrible. I have to spend a lot more to fix the problem.

  My car guys had to cut the flange to miss the steering column and cut and welded the exhaust pipe to match the angle. He called it "pain in the ... " Makes the engine looks bigger and sounds good, stopped the back fire.

  PERFECT LITTLE PIECES!

  First of all - when you're done with the installation and will first start up your car you won't believe your ride is still a V6. Almost like stock in idle - but as soon as you hit the pedal you unleash the beast! The sound is amazing! These little monsters are loud ;-) Installation took me a day - but there is an installation guide for them on the AM webpage - with that it should not take you that long for the installation. Alignment is good - follow the instructions - and the quality does look really good. All the weldings look like long-lasting. In my opinion the best item you're able to buy! If you wanna do a real pro-installation make sure you order an additional set of header gaskets with them and discard the old ones. Everything else you'll need for the installation comes with it! GET IT - before someone else does! ;)

  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.

  well built headers

  These headers look great and are well built. I choose them due to the good service that I've had from mac products in the past. I also like the fact that they are an equal lenght header. The coating is complete and the welds are nice and clean.

  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
