More Horsepower And Torque. Replace those restrictive stock 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 16 RWHP have been seen when installed with a matching MAC shorty Mid Pipe (see drop down option above).

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 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 long tube headers are designed to fit the 1996-2004 4.6L 2V Mustangs with either a 5 speed manual or automatic transmission, including the GT and Bullitt models. MAC Performance recommends using a MAC shorty Mid Pipe for the best performance gains.

Technical Note. This MAC Performance product is not legal for use in emission restrictive states.

Gaskets Do these come with new header gaskets? if so are they durable or junk?

  • No they don't. These MAC Long Tube Headers feature 2-1/2" True Fit Collectors that eliminate the need for gaskets.

Can I only use the Mac pro-chamber with this? Or can I use any brand of shorty x-pipe?

Teddy09

  • When installing Long Tube Headers, you want to stick with the same brand shorty mid-pipe as LTH for the best fit. The MAC pro- chamber would be a perfect match to these Long Tubes. You may be able to mate these MAC LT Headers with another brand mid-pipe, but there would most likely be some modifications needed. Hope this helps!

Will these headers fit a automatic car with no modifications?

Anonymous

  • These headers are designed to fit any 1996-2004 4.6L 2V with an automatic transmission with no modifications besides a new tune since long tubes will change the airflow from the stock shorty headers.

What is the clearance with these headers if I need to do transition work? Will I need to pull a header or loosen any up or will they leave enough room for clearance?

CrowdHunter

  • This really depends on the work being done to the transmission. In order to drop the entire transmission you will need to disconnect these headers at the mid pipe and possibly at the manifold to shift them enough for the transmission to come down.

Will these fit a 351 Windsor? My 1998 GT has a 351 swapped into it, and its been a pain in my rear trying to find headers for it. I also have a C-6 tranny swap as well.....it's complicated I know. Any help would be greatly appreciated! Thanks

Spicoli

  • Hi,These MAC Chrome Long Tube Headers will not work with a 351 w we do carry the BBK Chrome Long Tube Headers 1-3/4 in. Item #56203 and the BBK Chrome Unequal Length Shorty Headers Item #56212 for 351 swapped Fox body Mustangs We Can Not guarantee fitment on a 98 gt since the chassis is much different on a Fox, you might have to get a shop to make some custom headers.

Do these have a spot to connect the egr tube? I did not see a spot to connect the egr tube to these headers.

    not sure what to say

    they are a very tight fit... i dont know if being a convertible has any bearing on that, however I was going to install them myself but couldn't jack my engine up high enough or find the time to finish the job. So I took it to a shop, and after having more than half of the work done on their end, they found a way to charge me over $500 for labor after I told them exactly how to install them and they told me they didn't try to do it that way at first. It seems like a good product, but the headers are still leaking from somewhere. I'm honestly mortified with the whole experience. They are a bit quiet, don't make a lot of noise at idle or low RPMs which I think is good if you want to run an o/r mid-pipe and not get pulled over by cops. Was really pleased with the sound until i realized my mufflers were hanging down and re-upholstered them before traveling to NC (~5hrs) and the car was just super quiet, like i might as well have not really installed them =/ (the shop did an awful, awful job. They didn't even do what I paid them to do and my car didn't run when they told me it did after asking them if they'd driven it)

    Sounds fantastic espially paired with some good mufflers. Looks great from under the hood and under the car. Only problem is the pain it is to get into place. Be prepared for a project. But the end result is definitly worth it.

    Great Looking; Will be Nice once I drive my car in two weeks.

    I've done a complete swap from a 3.8 to a 4.6 and just wanted to say that although its been a lot of work its been really fun. I've had two MAC products in the past on my 3.8 and have always been impressed. These headers are also great looking and will peform much better than the stock manifolds so in my case since i needed a K member it was a no-brainer. I tried posting my pics but couldn't figure out how to save them as a fiel that would be uploaded. Def worth upgrading the exhaust while you have the entire engine out. Can't say much for sound yet, but will in a few weeks, but I know I won't be dissapointed.

    Great LT headers for the money

    These headers are hard to beat for the money. I love the tone and power it makes with the rest of my exhaust (MAC O/R h-pipe, Flowmaster catback). I was thinking of going with BBK LTs but after hearing horror stories at first I was hesitant, but it didn't really matter since I had an Automatic I had to get the Mac LTs. Don't let anyone tell you shorty headers give you the same power as LTs its hogwash, get any kind of LTs over shorties anyday you will be happy, I know I am.

    MAC LT Headers are BEAST!

    I couldn't believe the gains these headers made on my 02 gt. Huge difference in throttle response and overall performance. Absolutely love them! Not to mention the deep raspy tone that turns heads. Fortunate to have friends at RUSH Automotive in Austin who installed the headers. In addition, they built and installed a custom off road X pipe set-up..headers to chrome tips. Couldn't be more pleased with the MAC headers. Feels and drives like a different car. Big props to American Muscle for quick delivery and for offering such great products at a great price. One thing - you need a branch in Austin, TX! Thanks!

    Awesome Value!

    In spite of what so many others say, you CAN do this install by your self, in your garage, with common hand tools. I did min alone and it was fairly simple. If you take your time, (about 8-10 hrs) it's not that difficult. Utilize patients and common sense. The fit was excellent, and the finish was decent. The sound improvement was awesome and the mid-high RPM power gain was the best part! Would definitely buy again! As always, AM's shipping and customer service continues to be the best in the business.

    Sweet Headers!!!

    Do yourself a huge favor and don't even bother trying to install these things on your own!! Shop recommended!!! The difference I could hear from my stock manifold and stock h-pipe is night and day! With these, MAC O/R Prochamber and Borla Cat-back exhaust you'll get a exhaust note that will seperate you from the rest of the stangs out there! Reminds me of an old Hot Rod!!! Won't be dissapointed with these headers!

    Amazing sound Great Gains

    I really can't judge the performance of this product honestly by itself, because it was put on with a new motor and whole host of other bolt ons, but after speaking with a Mustang Magic top tier tech, he told me that these pypes are his recommendation because of their price and the fact that on the dyno the same car with headers like BBK which are almost twice the price may only give 1-2 more HP and thats including the fact that factory motor tolerances can be as much as +/-10% HP, the sound of these combined with my MAC pro-chamber Xpipe and existing SLP Loudmouth2 catback system is amazing.

    Smart Engineering in the Tightest places

    I installed the MAC's Headers onto the engine and then installed the engine into the car. The steering shaft fits between the inboard and outboard set of headers and fell through the opening as the headers went by the steering location. There is a good inch of clearance all around the steering shaft, without the restrictions imposed on the competitors tubes such as square indentations that still rub the steering. The pipes flow through the open space in the car and look as though they were constructed on the car. A Great Value and they sound as good as they fit.

    Decent headers for the money

    They were a pain to install in the driveway, I would recommend letting a shop install them as a lift would have made it easier. They sound great and on my 96GT they definitly helped, as that engine is already behind the 8-ball. If you have the money ceramic coating would be the way to go, underhood temps are hot, to say the least. But mine is a weekend warrior car, so it doesn't bother me. Definitly get a toon ASAP to get the most out of them.

    These headers sound great and were a simple install. They bolted right on with no problems and I also recommend the Mac prochamber to go along with the headers to have a greater performance and sound experience.
