Are shorty headers worth anything?

  1. JBAs for SOHC 4.6 are 1 and 1/2 inch primaries. The DOHC models are 1 and 5/8. The FRPPs are 1 and 5/8, but I don't know what the BBKs are - they haven't been released yet.
  2. bbk

    Brothers sells the bbk shorties they have been releasd I have one of their magazines. They have 1 and 5/8 primaries as well and they look somewhat like a equal length header.
  3. My JBA headers and BBK H-pipe were worth 30 RWHP for me, so I would definitely say they are worth it. Also, the sound is awesome with my Magnaflow catback... :nice:
  4. sorry for such a late post:


    my other mods besides the JBA ceramic coated cat4ward headers are:

    k&n fipk 2
    steeda underdrive pullies
    magnaflow x pipe
    custom made catback

    I got a lot of heat for my dyno, but what you said, and the 2 other dyno sheets are true, but anyway, my point that JBA headers do give significant gains. However, I would have gotten LT's if it weren't for california's smog laws. I also wouldn't have done it if i could go back...its kinda expensive...but im not complaining about them :nice:
