I was thinking about adding headers to my Ram with the 318 motor. I currently have straight pipes with a high flow cat. Will headers add any more power and sound? Will I have enough back pressure after adding headers? If anyone has this kind of setup I would like to hear about it. Thanks.

 

I don't have that set-up but port matched headers will promote much better air flow. That coupled with your dual exhaust will give you the most power and performance. On my 350, it produced 30 HP to the wheels.
