Description
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.

Please Note. The MAC Performance Long Tube Headers requires the use of a MAC Shorty Mid Pipe for proper installation.

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

SLP I'm still trying to put together the best exhaust and was curious if these Mac Longtubes will work with the SLP Catted Shorty X-Pipe and Flowmaster Outlaw Series Axle backs? Thanks AM

going2ownastangsoon

  • If you purchase the Mac Long Tube Headers, you want to stick with the MAC Shorty Mid-pipe for proper fitment. The axle-back does not bolt directly to your mid-pipe so you can choose whichever system you'd like. Please contact us if you have additional questions!

Can you use your stock catalytic converters with these headers? I'm trying to get the most bang for my buck and these headers are a good price, but I'm also trying to stay within my county restrictions. I have to have cats and most full exhaust systems are either off road applications or more expensive than what I want to pay.

Can these headers be used with a Roush M90 supercharger? Can these headers be used on my Roush 428R with the M90 supercharger? I also have a Steeda cold air intake, 2.57" supercharge pulley, 90mm idler pulley, 90mm mass air sensor along with an SCT X Cal 3 Tuner with custom tune installed. If these headers will work do I need to re tune my Mustang for these headers and would I need to replace anymore of my exhaust system as I am running a Roush off road exhaust system. Thank you, FG.

  • If you wanted to make the most of all your mods you shood do a retune but not required. You will also nee dto change the mid pipe to a shorty style

    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.

    Badass headers...not disappointed at all

    these headers made my car feel so good.....I took out my cats during the installation, my car is the loudest car at my school now, and you can definitely feel the difference in horse power

    A great buy for the blue collar guys..

    Really love the deep sound it added to my exhaust, more bass less crackling of the mufflers. I picked up half a second in the 1/4 mile so the power added has proven itself. I was told by a local pro to reuse the factory gaskets....don't. Had a leak so I bought great quality gaskets and eliminated that issue quickly.

    Great Product

    Great product. The price was great, and i had a shop install this for me. I also had the rest of the exhaust custom made, and i have pype bomb axel backs on it as well. It sounds great. I def. feel the difference with the headers installed. The stock manifolds were so restrictive. Gave the car a nice deep tone, and a muscle car roar. I love American Muscle. As a side point, don't forget to order o2 sensor extenders from AM also...you will need these to connect the o2 sensors to the headers. The stock wires are not long enough. I forgot to order them, but had AM ship them next day for me, and i got them installed and the car is running perfect. I recommend this product.

    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.

    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 $$$
