Description
More Horsepower And Torque. Replace those restrictive stock 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 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.

I love these long tubes. Great power gain easy install and look great. The only problem I had was that they arrived a little dinged up but who cares they are going to get dinged up eventually anyway.

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

  • 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!

    Good headers ... DROP THE CROOSSMEMBER

    Good headers but if I had to do it over again I would drop the crossmember and it will cut down on the install time drastically it can be done in one full day of non stop working

    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!

    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.

    Great Header

    I originally bought these for my 96 GT, but sold it before install. Recently installed them on my 02 GT convertible. I have to drive an auto, so these were the only LTs for me. If you have a vert, I definitely recommend shop install. After watching what they had to fight with to get them in; doing this in my garage would have been a challenge. The shop had to remove the vert chassis brace and lift the engine to get it in. Took them 2 days of working to get both sides in. Shop recommended using alum performance gasket, not the Ford racing gasket. Installed the LTs with the matching prochamber H-pipe and the car sounds good. Car had Flowmasters on it when I bought it, but they're not 40s. Next purchase...after cat 40 kit!
