What you are doing is removing the exhaust back pressure valve from the outlet side of the turbo. All that it does is close when the vehicle is cold to help it warm up. I did it to my truck after having it for 6 months or so and never noticed a difference in drive-ability or warm up time. I did notice a drop in exhaust gas temperatures.
:whs: only I did mine within the first month of owning her..I could not stand the howl from a strait pipe or loss of power when it closed up..no diff's in warm up time at all...when you do the pedestal you need to take flapper out of the turbo outlet as well..
