Review & Installation Video

Review & Install Video

The MAC 1-5/8 inches Long Tube Headers in chrome are available for any '96 to '04 GT owners who's looking to pick up some noticeable power gains as well as a sweet sound improvement with one of the more affordable options in the long tube category. These are the chrome options as opposed to ceramics, so for the guys who don't mind the rainbow color after they run over time and for those who are on a tighter budget. The installation for the long tubes is extremely lengthy and heavily involved across the board. Expect three out of three wrenches on our difficulty meter which I'll talk a little bit more on later on. Long tubes are so effective in improving power because the exhaust gases leave the cylinder with more speed because they have more time to gain velocity, thanks to the longer tubes. With this particular set, you'll see results in gains of up to 18 real horse power and about the same with torque which is definitely a plus. We always want to consider that other power adders can really maximize the potential, not to mention the effects a tune would have on something like this for your GT, although it is not required. Sound is an entirely other aspect because long tube headers are absolutely unbeatable for a true muscle car sound, of course, in my personal opinion. This in combination with the MAC Shorty Catted H-pipe will produce a deeper intimidating growl while combining it with the Catted X-pipe will give it a bit louder and raspier sound. Any off-road pipe combo will be a bit raspier since there isn't any restrictions in the mid pipe with no Cats. You can customize the sound, though, obviously by picking and choosing a Cat-Back setup that fits your personal preference. Personally, I'm a big fan of the Borla Stinger S-type Cat-Back because it's not too overbearing but it really makes a huge impact on your aggressiveness as I've had on my '95 Cobra. Obviously sound is one thing that is easily changeable to each person. While we're on the topic of restriction, these are made from 1-5/8 inch mandrel bent tubing completely unrestricted and gets a free-flowing air movement from the cylinders to the MAC Shorty H-pipe or X-pipe of your choosing. The 16-gauge tubing doesn't have any kinks or rough bends to rob you of any power. You'll notice that the chrome headers will start to discolor after being exposed to the engine heat and exhaust gases for so long, so they'll start to turn a bluish rainbow color. Obviously, the chromes all across the board are going to be guilty of that, not just the MAC ones here. As far as performance goes, that is completely unaffected by the discoloration it's simply an appearance change. Although that doesn't happen with the ceramic coated set so if you're in a lot of car shows and you're looking to keep your engine bay looking as polished and proper as possible, you might want to pick up the ceramic version instead. If you're like me and you don't really care about the color and you just really want to save a few bucks by getting the chrome option here, this is definitely the better choice. The 2-1/2 inch True Fit Collectors that MAC integrates into the systems, as you see here, eliminate the need for gaskets that are sometimes needed with collectors of ball shapes and to properly seal the flare end of the mid pipe. Now, this takes away the headache of a leak or blown out collector. While we are on the topic of gaskets, I would recommend picking up a set of Ford performance header gaskets for the other end. They are known to be the most reliable options, more so than the ones typically found in long tube header kits you get from those brands just like MAC. Obviously not a hundred percent necessary, they just are a little sturdier than most. I also want to point out just again you absolutely need to match these with a MAC Shorty mid pipe of your choice but no other brands. Stock length mid pipes will not work with long tubes nor will any other brand of mid pipe. They won't properly match up and they'll require modification. Just make sure you stick with the Catted Off-road Shorty H-pipe or X-pipe from MAC when you're picking these up. As I briefly mentioned in the beginning, these are one of the most affordable long tubes available in the category currently for the SN-95s and new edge GTs. For just about $450 bucks you'll get a sturdy set of chrome steel long tubes that'll definitely get the job done. In my opinion, they are a steal for the price considering the construction and the materials. If you're more interested in the ceramic look, however, those are running just about a $100 bucks more than these. The Kooks option offers the best materials on the market with 304 stainless and they have a very unique sound with their added merge spikes but that comes with a pretty serious price of about double the MAC option here so it comes down to budget for sure. These are, no doubt, a pain in the butt to install because they are so involved and require a certain amount of mechanical expertise. They will definitely test the entire toolbox and take the better part of a day to complete whether it's at home or in a garage or shop. If you don't have a helping hand on deck or enough experience to tackle it yourself, there's no shame handing this one over to a professional to get them safely and properly which is why you might want to consider tacking on installation cost to the final cost of this product alone. With all that said, expect full three out of three wrenches on our difficulty meter. Several hours, if not, with the majority of the day, to get this one done. Also, before I let you go, you might want to look into a set of O2 sensor extensions if you're looking to stick with your stock sensors. If you're looking to eliminate to check engine light with a quick fix, you should invest in a set of MIl or MIL eliminators to plug right in which will take care of that itself. MIL being Malfunction Indicator Light. Or you could take it a step further and pick up a custom tune which would not only shut off the light but will help you bring out the best in your setup and maximize the performance I mentioned earlier. That, however, is not required. All right and that just about does it for this one so if you're the owner of a '96 to '04 GT, you might want to check out the MAC 1-5/8 inch Chrome Long Tube Headers which are available right here at americanmuscle.com. "

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.

fitment issues with automatic trans? i have seen on some of the forums that people are having fitment issues with these headers on automatic transmissions. is this a new revision of the header? because i want to buy these but i don't want to drive down to the shop 30 minutes away to find out they won't fit. also, will there be any ground clearance issues if i pick these headers up with some H&R SS springs?

brozay

  • According to MAC, these will fit both the manual and automatic transmissions with out any problems. We've also heard nothing but positive feedback from our customers in regards to these long tubes properly fitting their automatic transmissions!

My stang is lowered 4 inches, will these scrape pretty bad??? I was wondering if anyone else had a dirt nasty low mustang with coilovers with these, I love my stance, but it's time for headers. Thanks!!!!!

ZacharyDavis

  • The MAC 1-5/8 in. Chrome Long Tube Headers, as with all long tubes, will take up some ground clearance. Unfortunately we do not test any products for fitment on Mustangs lowered more than 2", so we do not know how many clearance issues you would have, however these due tend to scrap speed bumps when dropped 2" if going too fast.

    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!

    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.

    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)

    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!

    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.

    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.

    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.

    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.

    Product is good quality for a budget builder. Install took me and a couple friends the greater half of a day to install. I recommend if you know how to do it and have proper equipment then go for it. If not then I recommend you take it to a local muffler or performance shop and let them bust the knuckles. It may cost more to do so but it will take a few days if you don't have proper equipment or tools.
