Do I need 02 extensions with these? If so r they included?


  • Since these are long tube headers, you will need O2 sensor extensions. They are also not included with the purchase of these headers.

Will these fit on an 04 gt convertible with an automatic transmission?


  • Yes, these JBA Ceramic Long Tube Headers should fit any 2004 Mustang GT.

Will these scrape on 1.5" lowered GT? Will these scrap on a 1.5" lowered 2003 Mustang GT? I know my X pipe hangs really low and does, but the headers scraping wouldn't be good!


  • Just go slow over speed bumps and you will be fine.

    JBA Never Fails!!

    To start with, this is the best deal you will find for the titanium Ceramic version of these headers. I bought these headers because I wanted a little more bang than you get with shorty headers, and like a lot of people, I did NOT want to worry about ground clearance. They went on without having to drop the K member too! The driver side was a piece of cake, and the passenger side... Well that was a different story. You have to remove the left motor mount and jack the engine up a few inches to squeeze the header up there. They came with very nice felt gaskets too. Needless to say tightening the bolts was time consuming ( got them in 1/16th of a turn at a time haha) I can very much feel a difference in the mid-range power, It really puts me in my seat now when I get on it in second gear. The sound is very clean too. I have a custom mid X pipe with slp high flow cats and slp loud mouth cat back. The idle and acceleration sounds mean! (Cams next for sure!) The only issue I had is the EGR tube did not thread up perfect and you can hear an exhaust leak from it. It's no big deal to me because I just had Bama send me a tune with the EGR deleted. I removed the entire tube and valve assembly, and made a cap for the intake plenum and welded the hole shut on the header. No leak now! Plus the engine bay looks neater. It a win win situation if you ask me. (I know my car might lose a few MPG’s, but oh well, I didn’t buy a mustang for efficiency) All in all, I’m very happy with the headers, they look great, sound great and feel great. Plus, they fit on Manual and Auto Stangs!

    They are ok.

    I bought these headers because my pacesetter long tube/ x pipe scrapped everywhere (car is barely lowered). With these JBA I do not scrape at all. I personally didn't like that the flange wasn't flat I feel it will cause exhaust leaks down the road. The fitment is honestly way worse than my 250 dollar pacesetters. They wouldn't clear the frame on passenger side and you can't install the starter. We had to dent it up a little to fit it. The driver side would not clear the steering shaft even though they already dented it from jba factory. My pacessetters slid right in. I don't think these should be 600 dollars. Maybe 400 but all and all I'm happy with the ground clearance. Just bad fitment.
