I have a lowered 2wd ram 50 with the 2.6, I have a Doug Thorley Header and full 2.5 exhaust matched with a Weber 38. I find when I switched to the weber I gained lots of low end torque... Or at least it feels that way cause both the butterfly's open at the same time so it gives wicked throttle response and with proper jetting and a good tune it runs on fumes if you are easy on it.

That is why I am looking for one for my 4wd ram 50 right now
