Re: downpipe stuck and won't come down through firewall
If its the new larger downpipe that's being installed, It needs to come up from the floor to the turbo. In some cases slight firewall adjusting (hammer the clearance) may need done. My 4" turbo downpipe went in just fine on my 7.3, its tight but fit just fine. Don't torque all the clamps down until its fully installed turbo to tailpipe so you can twist & adjust it all, then start from the turbo clamp & work your way back.
