Notice any difference in performance? I know when I did a complete refresh on my 335d at 100k it was like I was driving a new car! Way more response low in rpm!

I used the OEM Continental hose but will probably refresh it all again with thicker hose when it's needed, OEM lines seem to have a pretty short lifespan.
The actuators and converters were the meat and potatoes of what I did with this vac line refresh, pretty much everything on the hot side has been replaced. Good tip on the vac pump gasket.
No real difference in performance TBH, I don't think my lines were leaking just in rough shape and getting worse. Curious to see if MPG goes up with the EGR bypassed.
