  easy install

  excellent fit and maybe I am a little old school but I really like the chrome finish, removing the motor mounts make the install a breeze,

  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.

  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.

  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.

  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 $$$

  CRAZY LOUD!!

  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 Longtubes

  They look good under the hood... they are one of the few brands with the 1 7/8 primaries ... good bang for the buck ... i had some 255 wide rear tires couldn't hold traction in 1st 2nd and hard chirp in the 3rd... got 275s now much better.. great quality to me.. little bit of a tight fit by driver side steering components.... but all in all good buy!!

  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!

  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.

  • Response from AmericanMuscle

    Installing these Long Tubes and the mid-pipe, you definitely should be feeling the performance gains. We highly recommend getting a custom tune so that you can feel the full potential of these headers. If you have any questions about tunes, please give our Bama Specialists a call!

  Headers

  Really great headers but came in contact with the steering linkage so a minor bent was needed

  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.
