JBA Shorty Headers
JBA Shorty Headers I havent heard that much about these headers...Does anyone have them on there car and if so do they now how much H.P. gain they got from them?..I have heard up to 35 H.P on induction engine cars...I am looking into getting them but are they really worth it...And I dont really want long tubes... <img src="graemlins/gr_hail.gif" border="0" alt="[hail]" />

Re: JBA Shorty Headers I have these on my TA since my car is lowered. The quality, look, and fit is perfect. JBA always makes a good header. As far as power goes though the gains are minimal. 5-12 HP is probably what you can expect. Some here on the board have dyno'd them to 0 gain. So you need to decide what you desire most: The most power or the nice look of a lowered car. It's a trade off. Good Luck.

Re: JBA Shorty Headers I was looking into JBAs a while back. I too saw many people that reported 0 gains, thus I chose to just keep the stock manifolds for now. I’m having a hard time deciding on a set of headers, so I’ll just wait <img src="gr_stretch.gif" border="0">
First I didn’t want LTs, then I did, and now I don’t again <img src="images/icons/rolleyes.gif" border="0"> I have a hard time picking mods <img src="gr_grin.gif" border="0">

Re: JBA Shorty Headers There was an improvement in design on the exhaust manifolds for the 2000 and newer cars. For 98 and 99 you can expect about 10-15hp increase with the JBA's. The manifold design was one of the main reasons 98-99 LS1's were rated at 327hp and not 335hp. (They also changed the cam design, using the same as their GM truck cam to allow them to remove the EGR system and the addition of the LS6 intake manifold.)
I have the JBA's on my '99 and the fit and finish is just about perfect. They are very good quality and look 100% better than the manifolds. I also did feel a slight increase in performance and the exhaust note is improved as well. But I would hesitate going through all of the trouble if you have the newer manifold design.
