Already installed the Airaid PowerAid Throttle Body Spacer, and Airaid Intake System. Just looking to install JBA Cat4ward Headers, but ive heard from every place i go to, to not install them, they all say they will viod your warranty they leak, or throw codes, and you loose gas mileage!! So now i want someone that has put headers on there 2009-2012 5.7 hemi.. What should i do?

Also looking for some tips for the rest of my exuast, and i can't find a good performance chip set for the 2012 ram, guessing thats because of the new tranny..
who told you all that? the same person that sold you a t/b spacer? My JBAs are on order and I'll add the BRH's thread after my install. On a side note, I've been running JBA longtubes on my car for 3.5 years now with no problems.

the only reason why you'd lose gas mileage is b/c you start driving it harder. your exhaust will sound better and you'll like the new found power. JBA short-tube headers only replace your stock exhaust manifold and nothing else (i.e. cats, O2 sensors) is moved so you won't throw any codes. if you use MOPAR exhaust gaskets and torque the bolts in the correct sequence to the correct specs they will not leak. they won't void your warranty. My vote is to install them and replace your muffler with a magnaflow and it'll feel and sound like a whole new truck.
