This up pipe is for Ford trucks w/Round Body EGR Cooler (models F250, F350, F450, F550 Powerstroke 6.0).
This exhaust Up Pipe is a common failure on trucks with high mileage and age.
The exhaust bellows will crack which leads to exhaust leaks and loss of low end power due to reduced exhaust flow to the turbo.
Black carbon around the passenger side firewall is a sign of a leaking or cracked up pipe.
