Leaky up-pipes can rob horsepower, increase EGT’s, and will cover the back of the engine compartment in soot. PPE’s new up-pipes feature an improved bellow design which is much more robust than the problematic factory design and intended to last the life of your truck.

I read about difficulties with fitment issues on these Y pipes but they went in decently. You have to install everything very loose and then work around the turbo to tighten it all up. One tip is the turbo pedestal can move slightly if loosened so try that before you give up and force them into place. Also note there is a gasket needed at the two bolt flange and mine didn't come with it but an oem replacement fit no problem. I'd also recommend doing something for the heat protection. I thought I might be able to reuse my oem heatwrap stuff but I couldn't.
