More Horsepower and Torque. Now you can improve the performance of your V6 Mustang with a set of PaceSetter Black Long Tube headers for power you can feel throughout the RPM band. These Long Tube headers when combined with a PaceSetter shorty mid pipe will greatly improve your Mustangs exhaust flow for an increase in horsepower, torque, and throttle response.

Durable Construction. Manufactured from 1-5/8" mandrel bent 16-gauge carbon steel tubing for strength and unrestricted airflow, these PaceSetter Long Tube Mustang Exhaust headers feature CNC-machined 3/8" thick header flanges for additional strength and an OEM fit.

Black Painted Finish. These PaceSetter Headers feature a standard black painted finish, which is used to protect the headers during storage and shipment, as well as providing an aggressive appearance to your engine bay. This is not a heat-resistant coating.

Recommended Upgrade. To realize the full power potential that these Long Tube Headers have to offer, AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

Application. These PaceSetter Long Tube Headers are designed to fit the 2005 to 2010 Mustangs equipped with 4.0L V6 engine. These Long Tube headers will require the use of a shorty style PaceSetter Y-pipe for proper installation (See drop down option above).

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

Custom Dual Exhaust fit question. I have a custom dual exhaust set up on my 2009 V6 and I am running an X-pipe with 2 inch intakes from the headers. It is swapped right in place of the stock mid-pipe. Would these headers work with my set-up? If not can you reccomend something that would work better with my system? Thank you so much for your help.


  • If you have stock cats and pipe then any Shorty Header will bolt right up.

Headers w/ JBA catted shorty h pipe Can these headers be used along with the JBA catted shorty h pipe. For the h pipe it says it can be used only with JBA long tube headers but I was wondering if the h pipe will work wit-h these headers because they are also long tube. Please help me!


  • There's a review on these from November 2, 2011 saying the JBA catted h pipe does fit.

Mac Mid Pipe I bought the Mac Pro Chamber Mid-Pipe for the v6. would these headers work with that mid-pipe?


  • The MAC Cut and Clamp Pro Chamber is designed to bolt up to stock manifolds or shorty headers. Unfortunately, that mid-pipe would not be compatible with these Long Tube Headers.

H Pipe will the GT pacesetter H pipe work with these to avoid using the Y pipe?

How much horsepower we talking about here? I care about performance over looks ANYDAY! My car is pretty heavily modified but is missing headers. How much horsepower could I estimate will be added to my car with these babies?


  • Long tube headers are estimated at 20-30 HP gain when combined with the recommended custom tune. Hope this helps!

    i agree with thiguy65, if your looking to get the most out of your v6 then get this product. after i installed the LT headers I've noticed a huge increase in performance. if your wondering what i was, then yes, the JBA Catted Shorty H-Pipe (05-10 GT) does fit!

    This product was worth it.

    If your looking for some serious gain in hp or torque, I would recommend getting this product. I got a 2009 v6 with pacesetter long tube headers, gt catted h pipe, and borla s-type catback. My exhaust sounds amazing and I havnt even got it tuned yet. Still saving up on that SF3 tuner, I already bought my JLT CAI cold air intake but havnt installed it yet cause a tuned was required. But get it, its worth it! Dont get that shorty y pipe, go for dual exhaust!!

    Great product

    I had local shop install and got a great deal. He had no problems fitting and installing. He did have to remove cats, if you want cats they have to be relocated. I would advise relocating them myself(I'm getting o2 extensions here at am to make it simple and easy). At the moment my car sounds absolutely terrible but that's because that cats are off and still have Flow master 40's on(which i hate btw). But i have herd a V6 with these same long tubes and cats with no muffler and it sounds amazing, will have same set up shortly. All together I do feel a gain in the mid power, will feel more with good tune. no cats are throwing things off for my car and it feels like it doesn't quite know what to do with the more open exhaust but again tune will fix that.

    Worth the effort!

    These headers are everything I hoped for! Great gains in Hp/Tq and sounds amazing. For the cost you cant go wrong. Install was a pain because of limited space but other than that its pretty strait forward. I got the high flow cats go with. Only downside is my pypes x-pipe did not line up properly anymore so i ended up having it bent a little and then welded in. If you are wondering how it sounds ive uploaded videos on Youtube under spartan1492. All in all very satisfied!

    Best bolt on Mod out there!!!

    So I bought these about 6 months ago with the intentions of putting them on that weekend. I've done just about every bolt on modification out there for my V6. Total installation time was about 5-6 hours and that was by myself. I bought this V6 as a repo car with 100k miles on it for 4 thousand bucks. I felt like a got a good deal, it was a piece of junk when I bought it. Thanks to places like American muscle I've turned into in a project car, I'm constantly turning heads everywhere and getting compliments almost everyday. I completed this entire project by myself, no help at all and I completed it on jacks. Prior to putting this in I had the true dual system installed about a month before which gave my v6 a bang for its buck but I wanted more and I knew freeing up those terrible manifolds might do the trick. So I followed the instructions and unbolted my h-pipe and removed my cats, didn't have to lift the engine or motor mounts, trust me I didn't have the right stuff to do that anyway lol. A couple of hand tools and patience and I had the new long tube headers on, I wiggled them down in through the engine bay, wasn't simple but with enough moving and wiggling it worked! Make sure you bolt on the EGR pipe before putting the driver side header on, this will make life a lot easier, and make sure you take it off before trying to pull down the old manifolds, that was the biggest problem I ran into. Keep in mind, I had to put the CATS back on which I replaced with smaller ones bc you can't reuse the stock cats, they are bent wrong for this setup, even with the cats "keeping it legal" its sounds crazy, I drove it around with open headers and I sounded like a drag car. My system sounds better then a 5.0, trust me, it's louder little to no drone and I can rip into the higher RPMS and turn heads on the interstate, it's scary but still a good daily driver! I love this website, I used to be a noob who couldn't change a lightbulb and now I've learned how to do tons of stuff! Thanks AM!

    Great Performance Gain!

    I am very happy with my choice in going with the longtubes rather than the shorties. I was amazed at the mid range power gain from these, especially with the tune. I would recommend these to any v6 owner.

    Great sound

    Bought these around 5 months ago, me and my buddy installed them and the off road y-pipe in about 3 hours with a jack and some hand tools. The hardest part of the install was taking off the old cats. I'm currently running these headers, off road y pipe, cutout before flow master 40. With the cut open the car sounds awesome! And with the cut out close it's veryyyyy raspy. Three people asked me if I put the new 5.0 engine in. (But they're not the smartest people) Performance was decent. I bought it mostly for the sound not performance.

    Pacesetter Longtube Headers for 2005 V6 Mustang

    I can say that this product is amazing overall!! The only things that i can say improvement wise is that I was not sent enough of the wire splices for the O2 sensors. Also, the EGR tube port on the new headers did not provide enough room for me to properly screw the bolt on without scratching the headers.

    for obnoxious drivers like me only :)

    I installed these headers along with the Borla true dual exhaust and i can defitnetly say it was worth it. Sounds like a V8 now and will break necks from miles away because its extremely loud and not the annoying ugly sounding type of loud, its growl is smooth when driving the speed limit, but as soon as you put your foot down it will scream. I actually had a guy in a Ferrari take the time to stop next to me and tell me that my car sounds beautiful. The only thing that disappointed me was the fact that the black look of the headers is pointless because the same day you're driving it home after installation the heat will completly melt it right off and its honestly not a good look under the hood.

    Great part with right tools

    The long tube headers were a great install on my v6 mustang. It took me and 2 other friends to put it on in about 3.5 hours. But before you install this be sure you have the right tools or is will be hard to do. You need a OEM o2 wrench which I rented from autozone. And you need another wrench to get the EGR pipe(copper tube covered in heat wrap) off the old manifolds. Also be sure and get the O2 extensions from AM because your stock O2's won't reach and the ones that come in the box the are some wires to solder on to make your O2 sensors reach. Other than that you need 13mm and 15mm deep sockets with extensions. Besides all the extra stuff you need this a great product and it gives the pony deep rumble in idle(sounds like its cammed) and you will definetly get people looking.

    PaceSetter Black LT Headers

    These headers gave my 06 stang a deeper sound and a little more pick up when i hit the gas! I didn't want to pay a kechanic to do it so i made it a weekend project with my dad. Took us a solid day because we had to do a little fabrication with the exhaust, but all and all it isn't the most difficult thing to do by yourself! The one thing I didn't like was how they didn't put high temp black paint on the headers, so the first couple times i drove it after installation the paint smelled pretty wrank burning off the pipes.....
