In the description is says " Not applicable to 3.9L V6s " Why is that? I have the 3.9 Liter 40th anniversary edition and its become a real pain to try and find a good set of headers.

  • It's about the carb certification in California for these headers. They haven't received a formal Carb certification for the 2004 model. It means that technically you can't install them on a 2004 if you live in CA. I did anyway and never had a problem to pass inspection because there is a carb sticker affixed on the headers.

Also what would the difference be between an air injected mustang and a non air injected? Just kind of confused when I saw "Does not accommodate air injection Mustangs" in the Specs

PapaRoach97

  • You shouldn't worry for that because if you had an "air injection" you'd certainly know about it. I installed these on my 2004 V6 and didn't have an "air injection" problem.

    The JBA headers are a great addition to any V6 mustang.

    I bought these headers to get rid of that annoying exhaust leak that many 99-04 mustangs develop at the manifold. They got rid of the leak, and the exhaust gaskets provided are great. I did run into a couple problems with the installation however. Since these headers are one solid flange, rather than the individual flange for each header port, I ran into fitment on the driver's side with the dipstick tube. Advice tho those who do purchase these headers, remove the dipstick tube, put the new header on, but let it hang from the studs by threading the bolt only enough to catch. Then, put the dipstick back in place and tighten the header. On the passenger side removal of the stock header is a little tricky with the EGR tube. Just remove the EGR tube from under the EGR valve, and remove the header and tube together. Then remove the EGR tube from the header. I recommend using anti-seize on the threads of the tube when putting it onto the new header. Other than those fitment issues, these headers are great. They definitely stopped the leak and my car has never sounded better.

    Good HP Gains

    It took about 3 hours to install both of them. I ran into the oil dipstick problem but I just cut a gap in the header so the dipstick will fit through it. Getting the EGR tube on the right hand side is tough though, once off its all easy. Noticed the difference in HP right away. It has a stronger kick and improved Throttle Response.

    jba v6 shorty headers

    great headers. but be prepared to run into fitment problems with your dipstick and having to relocate. other than that... direct fit and no problems with the actual headers being installed.

    Good addition

    These headers together with the free for life Bama tune from AM are really a good addition/replacement for your car. I took these because they are CA legal and my headers were cracked. Installation was intensive but not too difficult if you are organized and have the proper tools and I did it alone. The only problem I had was the dipstick tube but this problem is inherent to the tube not to the headers (this tube is sh@*). My car now runs smoothly, rpms don't collapse midrange when I change gear. It was worth the effort and saving the $ 700 mechanics requested to do the job. It took me about 12 hours to install.

    Look Great, Sound Great

    Installed these headers to eliminate the infamous Ford exhaust tick when cold. The hardware included is good quality, they included plenty of extra bolts and lock-washers, however they provided only 2 large washers when 4 were required. They do fit quite well, the only installation complaints are aimed at Ford and not at JBA. For instance, the engine oil dipstick tube will make your life difficult, and reinstalling the dipstick with the header is a two person job, one underneath and one up top. Tightening the lower EGR nut is also tricky without the proper tools. They do sound great, and help engine response in the lower RPM range.

    Great Upgrade!

    I got these headers along with the MAC Dual Exhaust Converstion Kit and I have a great setup!! I got rid of that exhaust leak and gained a meaner roar and better take off when I accelerate. There were problems with relocating the oil dipstick, but other than that easy day!

    Intense

    These headers are perfect, all hardware is supplied and information is accurate. The performance is great they definitely give the mustang a deeper growl and more low end power. Great addition to the 2000 mustangs whose headers are not the best. A must buy for all mustang owners that want performance.
