anybody running the JBA shorty headers and/or mid pipes? What hp gain did u see? Per title, wondering what you actually saw. JBA claims 20hp for just the mid pipes and another 18.5 for the shorty headers. If actually true I think I'm interested (especially if the gain were the total of 38.5). Appreciate any experience.

As far as JBA, there was a tread on Camaro5 a little while back where they actually lost power. I would suggest the Doug Thorley Shorties. I think the gain is between 5-10. You will not see the inflated gains they claim though. I personally have the DT's on mine. Did the install just before I put her in winter storage, and haven't driven the car in a while (November I think). I will be taking it back to my dyno guy as soon as Spring hits. Before the shorties. I made 383 at the wheels with the LMR intake and Corsa Exhaust (5th gen exhaust changes typically yield little gains compared to other Gens of Camaros). I have changed over to the Halltech intake tho (Noticed a difference with just that). Don't wanna take away from LS1 Tech, but there is a VERY large and strong data base on C5 where all these issues have been addressed.
