I have JBA shorty headers let say that I did not notice a difference is sound and performance. The sound is deeper than the stock for sure. Its really difficult to for me argue to about HP gains especially at what other are claiming.

The install of the shorties headers or any headers is expensive simply due to the fact of all of the differenct compotents that have to be removed in order to do the install. I do like my shorties but add in the cost of the install and well you just might as well get LT.

Be no means would I rule out OBX headers they do look like good quality.
