Still have high NOx after numerous component checks & repairs so I am seriously considering my 17 yr old CAT.
I measured the surface temp of the exhaust components after an extended, medium speed run.
Turbo housing = 450 (All temps are F)
Downpipe = 170
CAT = 250
CAT outlet pipe = 450
Further downstream 170

Do these temps show a healthy or weak CAT?
