Anybody know that the power difference is between them?? I know there is a big cost difference if the JBA doesn't make more power over the BBK then I'm going to save a few $$$ and go BBK.
If your concerned about price to power ratio, why get shorties in the first place? I know I will never buy shorties, to me its worth it to spend a little more for longtubes and get a bigger hp increase. my 2 cents
