More Horsepower And Torque. Replace those restrictive factory manifolds with a set of MAC Long Tube Headers to improve your mustangs exhaust flow and increase your Pony's horsepower and torque. Increases of up to 42 RWHP have been seen when installed with a matching MAC shorty Mid Pipe.

High Quality Construction. Constructed from 1-3/4" mandrel bent 16 Gauge Steel tubing so there are no kinks to rob you of power, these MAC Performance Long Tube 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 bright chrome finish for good looks and a durable long life.

Recommended Upgrade. To realize the full power potential that these Long Tube Headers have to offer, AmericanMuscle recommends a custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

Application. These MAC Performance Long Tube Headers are designed to fit the 2005-2010 4.6L 3V Mustangs with either a 5 speed manual or automatic transmission, including the GT and Bullitt models.

Will this product work with the bbk off-road xpipe for the 2006 mustang GT?

The MAC 1-3/4 in. Chrome Long Tube Headers requires the use of MAC Off-road Pro Chamber Mid Pipe, item 40041. The use of a different mid-pipe may work, however, due to differences in manufacturing tolerances and design there could be some fitment issues. https://www.americanmuscle.com/mac-shorty-offroad-prochamber-0509gt.html

Whats power gain over stock? im between these and a set of pacesetters

These long tube headers are advertised as creating an additional 42 RWHP when installed with a matching MAC shorty Mid Pipe and a tune. There will be some variation in overall power gain depending on other modifications and the tune applied.

How well will the chrome finish hold up? Will these headers rust out? 1 answer

Well considering these are headers, if you plan on driving, really at all, with these installed, you will have to clean them on a very regular basis to keep the finish.

Hi guys, Received my headers and pro chamber all the way down in New Zealand, thank you. I had to put prothane engine mounts in to solve steering shaft rubbing. Now the NVH at around 1500 rpm is horrible, with the stiffer mounts. Please...any suggestions...different mounts? cure for vibration? Thanks 1 answer

Hello! I am glad you received your parts just fine. Unfortunately I cannot think of anything related to the headers that would cause these other noises and vibrations. I would recommend sending us an email and we can try to trouble shoot or discuss some other things that could be causing this.

Do these need to be ceramic coated before installation to prevent rusting? 1 answer

The MAC Chrome Long Tube Headers (05-10 GT) do not need to be ceramic coated, but it is definitely a good idea to do so. The ceramic coating will help prevent rusting while also dispersing heat soak a lot better than a chrome coating can. Heat soak eats up a lot of power that the engine is producing.

I'm currently running stock headers catless H pipe and American thunder axle backs but I need to (unfortunately) make my mustang a little more quieter but also what to do long tube headers. Will this plus the MAC Shorty Mid pipe quiet it some but also give me decent power gains? 1 answer

The MAC Chrome Long Tube Headers (05-10 GT) will give your Mustang a more aggressive sound paired with a shorty mid-pipe. If you wanted a quieter sound, I suggest shorty headers, a catted H-Pipe and an axle-back exhaust that has a mellow tone. The power gains that you will get will all depend on what modifications you have already done to your Mustang.

Do i need any other modification for example 02 sensor extensions and will the tubes work for my 2010 mustang gt?? 1 answer

yes you will need o2 extenders , and either the mac pro chamber H pipe for long tube headers or like i have , 2.5 female ball collectors with 12" long 45 degree bent elbows to 2.5 i.d. band clamps , connecting to a xpipe back..

should i buy a ceramic or stainless steel header? 2 answers

I honestly don't think make much difference but you probably will get a lil more from the ceramic cause they stay cooler but my macs have been great and have not had any installation issues or heat issues that would affect anything bought some heat wrap and have not even needed it
Cant go wrong with either type. I have the stainless set , they turned a bluish color . A friend has the ceramic set , and it still looks new.. Thats all the info I have . Hopefully it help's.....

midpipe I just purchased these headers for my 08 shelby gt. Do I need to order the midpipe as well ? or would I be able to have the local exhaust shop make it custom ? Thanks AM. 3 answers

Your local shop might be able to customize a shorty mid-pipe to fit with these Long Tubes. However, the MAC Shorty Mid-pipe is a direct fit for these Long Tubes. There's no telling how much a shop would charge for all that custom tube work. I'd highly recommend contacting some local shops in your area to discuss your plans with them so you'll have an idea which option would be better suited for you. Hope this helps!
Ask your custom exhaust shop....The easy route is to buy the matching mid pipe from the same manufacturer.
A good exhaust shop can make it custom ... but it prolly won't have as good as flow as manufactured... but u will have to change up your midi with any long tube setup

Could I use any shorty H I was just wondering if i could use any shorty H pipe with these headers because I don't really want to spend the extra $400 on the Mac shorty mid 3 answers

Jhof, I apologize that I CAN NOT answer your question directly! But, I am going to give you my opinion on the matter. I think that if you really want to use the part in question that you should also use the part it was first designed to work with! I doubt that you will save any money or time by using another companies part! That's only my opinion/thought. Again, I apologize for the less than direct answer! All the best to you. And GOOD LUCK with your project how ever you decide to handle it. QWIKCARL22
you need to keep mac with mac
You would probably have to cut and weld the shorty pipe to work with the long tube headers. It would be cheaper in the long run to buy the H- or X-pipe that goes with the headers you want to buy.

Can you use the O/R Prochamber mid pipe with these? 3 answers

If you swap to these Long Tube Headers, you will need to install the MAC O/R Pro-Chamber Shorty mid-pipe for proper fitment. The standard length O/R Pro Chamber mid-pipe is meant for use with the MAC Shorty headers or stock manifolds only and won't fit with these LTHs.
Yes you should be able to if you have the shorty O/R pro-chamber. If not than you could call mac by phone ( they were super helpful) and see what options you may have.
The mid-pipe 'accessories options' recommends the use of Mac off-road mid-pipe. The link in the Description section takes you to MAC Off-road Pro Chamber Shorty Mid-Pipe (the same product that is at the 'accessories options'). This is what I ordered for my 2006 GT & will hopefully be installed in the next two weeks.

Great!....but

I’ve had these headers for a while, good perforance gain, good looking...but the fitment is not good at all. The driver side header was rubbing on the steering shaft even after having a shop try their best to fix it. Ended up getting polyurethane motor mounts to raise the engine a little and that did the trick!

They look great, but...

I bought these headers about a month ago, and AM was quick to ship. I wrapped the headers with titanium exhaust wrap, and they looked beautiful. I installed these headers myself, and it was a real pain. The steering linkage, starter motor, and both motor mounts must be removed, and the engine lifted slightly to allow for clearance. Once they're in place, the bolts are difficult to get to. It took me a solid day to install them (Saturday day afternoon and Sunday morning). Proud of my handiwork, I couldn't wait to get my car to the shop so they could cut and weld the existing off road x-pipe to mate to these headers. $250 and 2 hours later, it was done! They started the car, and I was grinning ear to ear. When I pulled the car off the lift I noticed it...a huge exhaust leak. The mechanics discovered the leak was coming from the rearmost primary on the passenger side. I figured I forgot to tighten a header bolt, so the next morning I was under the car again with the starter removed. I attempted to further tighten the bolt to no avail. It was tight. And then it dawned on me: the flange was bent. Hours wasted and hundreds spent on a subpar product. My only option now will be to remove the header, and have a shop fix the poorly constructed flange. To add insult to injury, I'm now getting horrible gas mileage, as the entire bank is running rich. I am hugely disappointed with this product, and I cannot recommend Mac to anyone.

Way loud

Like the other reviews say, almost all headers will improve on performance and exhaust note. The prochamber, for was a bit too quiet, so I used my old Xpipe and had to customize it to get a perfect fit. Now it ridiculous loud. But only when you get on it. Way better sound at idle too.

Mac long tubes problems!

Very disappointed in the fit and finish first set the flanges were bent so badly couldn't get them to stop leaking. Second set header rested on frame and on top of lower control arm. As a result I had a terrible vibration through out the car. Thankfully AM was very helpful in resolving my problems by helping me pick a different brand header!

Awesome old school upgrade

These headers were a breeze to install. They sound great and the performance is noticeable when paired with a tuner and O/R mid pipe. Because of the style of the hearders, my saggy stock motor mounts caused the driverside to hit the steering shaft. After some Polly motor mounts were on, there were no more clearance issues. I would suggest getting the mounts at the same time and installing them while your under there. It is easiet to install them while the stock manifolds are off and before the new long tubes are on.

MAC Long tubes!

First id like to say these long tubes were a pain to get in my 07 Shelby GT the drivers side header rubbed against the steering column for a while then got the header pipe rubbing against it adjusted. I defiantly got more power than expected and after I paired these with flow master super 10s its defiantly the loudest car in the county (:

good for the price

good deal compared to all the stainless $1000. ones. easy install if you take the motor mount brackets out, only problem was it jambed into the steering shaft, had to dent the header slightly and shim the motor mount a bit, then it was all good, noticed a little power increase. I would of bought kooks if I had the cash, but these are worth the $$$

These headers are the best bang for the buck out there. And IMO they are a lot better then those expensive ones. If you are thinking about getting these for your stang, do it and you won't regret it. The sound and finish off the product is outstanding. Even though all my neighbors hate me,I would buy these headers 100x over.

LOOK's , sounds & feel........

In a nut shell, overall a very strong 4.5 out of 5. Fit's directly with no struggle . They look sexy , yet strong . The sound...." awsome" .... Great rough , raw sound... Starts deep and smooth , as you open up the throttle , you can hear that rough raw tone, almost angry, very aggressive. I have these bad boy's running straight through to a Bassanni X pipe and Bassanni axle back system. Sounds very distinct ,original , haven't herd a Pony with this sound yet . I guess it's the exhaust combo I have on my 06 GT . Very happy , & strongly recommend !!!!

Mac lives true to the rumors.

These long tubes (off road) from Mac added about 35 RWHP after the dyno tune on my '10 GT. Previous modifications were; Roush CAI, Ford Racing intake manifold, Ford Racing 62mm throttle body, Ford Racing ported cylinder heads, Ford Racing hot rod camshafts, and Steeda under drive pulleys. Aside from the power gain, these long tubes sound low and throaty. I have the Mac pro chamber off road midpipe and couldn't be happier! I get a lot of compliments and questions on the exhaust set up. The shop owner even had a big grin on his face when he started it up for me when I was picking it up. The only slight negative I have so far is that the driver side header rubs slightly on the steering shaft when making hard right turns. It's not bad, just noticeable through a small vibration in the steering wheel. I think it's more of an issue in space rather than a design flaw. I've heard of MUCH more expensive brands doing the same thing on these cars. I guess something you have to live with if you want this modification. All in all, I'm in love with my car all over again. I wouldn't have done anything differently with it if given the option!

Sounds angry!

I will start by saying that this isn't something you want to do yourself if you don't have a garage full of tools and a lift. Luckily I had all that and it still took 7 hours. Real tight fit and I had to do a pretty good tear down of the undercarriage to fit them up, but when the job was done all I could do was grin. These headers paired with the prochamber are unbeatable. Sounds aggressive and gives you a very noticeable torque gain. Second gear just got more fun. Would definitely recommend.

Not worth it.

The fitment was okay,and the quality was what I expected for the price. Not bad but definitely not the best. Sound wise it's just not there. I was looking for a deep low tone so I coupled these headers with the Prochamber and Mac a/b. I have no complaints from the mid pipe back! These headers give off a tin can sound that is worth avoiding them all together. Performance gains are moderate at best, and after this trail and error I just can't see why somebody wouldn't just save up a little more scratch and go with a stainless or ceramic coated header! AM was Awesome as always! I'll be back to perfect my setup.
