I have the same motor setup, except for the efi manifolds, and while I can not give you any numbers on paper I would say it is enough to make it worth your while. By seat of the pants I can tell you that it is a very noticeable gain in horsepower and torque. I still have the stock exhaust log and with 35" tires and 3.55 gears I can run around all day in 4th gear without holding the pedal to the floor, which I couldn't do before. There are many people who have done these mods on this site so if you do a search you can probably get some actual numbers.
