I would like to know which one is best to change first? I have 05 dodge I do want to change both but may not be able to change at same time. And also which one yaw thank is best.

 

Well you already have a 4in exhaust. What do you have done to your rig?

 

Fill out your signature so we can see what you have. I would do the exhaust first. All you need is an MBRP replacement muffler, Donaldson, Aeroturbine, or you can spend the 500-600 bucks for a complete kit that you don't really need.

 

What do you meen yes have 4" I was think 5" turbo back

 

Don't waste the money of a 5" system unless you plan on adding some power!! Like a programmer(bullydog Crazy larry or edge, smarty). I added the 5" system on my old truck becuase I broke my factory 4" but it also lowered my egt's 150 degrees or so and that helped while I was running Crazy larry and towing!! I would still hit 1500 degrees no problem. Just look into a replacement muffler and a tip.... That's all you need for an exhaust.. Definately upgrade your intake... Get an enclosed filter though. Where I live it is windy and dusty and I was always cleaning mine. Look into the scotty.
