The only thing I did not have is factory warranty on the exhaust.  Give me a dealer that tells me that I can't have warranty on something else because I changed the exhaust.

Believe me, here it's better and safer to put back the oem exhaust if you need a warranty service on your powertrain, especially if you replace something like the OPF/KAT with sensors and whatever
If instead you need a warranty service for something not related to the powertrain, no problem of course
