2012 exhaust-headers reccomendation

Hey TW-first time caller-long time troll. Had my last yoda stolen and finally have my new rig a month later and im not so framiliar with the second generation upgrades. I will research later iKnow the information im looking for is probly on here i just wanted to be specific to my truck, maybe post a few pictures, who knows. I am interested in upgrading the headers and the exhaust, the catalytic converter if i have to. It is the 4.0 6 speed. I am looking to increase the hp as my first step was the cold air intake which is already installed. any other ideas i would love to hear. thanks y'all!

 

depending on location and budget, long tube headers and urd y pipe are the only thing that can give you a noticeable amount of hp gain. cat back exhaust will only give you sound and a minuet amount of throtle response.
