I have a 05 4.7 RCSB and want to get headers for it but dont know anything about the Gibson or the JBA headers. which ones are better the JBA or Gibson

 

Don't know, can't vote. I have Pacesetter LT's in my Hemi...

 

Hammer I dont think Pacesetter makes it for the 4.7L. Just the Hemis 5.9 & 5.2 4.7 gets bastardized again. I checked out both sites and it looks like the JBA's are better (no dyno sheet on 4.7)but I would suggest calling KRC Performance and ask. They may have Dyno'd your set up and could tell you. KRC's price is $599 as opposed to direct from JBA @ $771.

got JBA's on my truck an love them

 

Ive got Pacesetters... welded them to the cats and they are rock n roll. Quitea bit less money than JBA's and Gibsons.....

 

I voted for gibson, due to everything i have ever owned from them being awesome as well as their customer service.....
