Step 11:
Once the up pipe is removed you will be able to see/feel the V-Band clamp connecting the factory
down-pipe to the back of the factory turbo. Take the nut all the way off so you can spread the clamp far
enough to slide it over the flange. These clamps are under extreme heat and are usually baked on, use
either a small pry bar or flat head screw driver to pry it off.
Underneath the truck you will need a 16mm and 17mm ratcheting wrench to undo the bolts connecting
the down-pipe flange to the exhaust system.
The factory down-pipe is a two piece pipe, to remove the lower half of the down-pipe you will need a 15mm
deep socket and ratchet to remove the large band clamp holding the two halves of the down-pipe together.
Now you can completely remove the factory down-pipe from the truck.
