Is anyone running the Banks Power Pack for the 5.4L? They claim +25hp and +26lbft torque increase at the rear wheels. The kit includes the cold air intake and headers. I would like to know how hard it was to install, and if you saw the same performance increase?

 

Looks like a nice setup. Banks is very reputable so I would trust their numbers. I wonder how hard it would be to change the exhaust manifolds on our trucks, looks like a tight fit.

 

- the pipe is stepped up from the oem 2.5" behind the y to 3" to the muffer, it is stepped up from the 3" just outside the outlet of the muffler to 3.5"
