Oil In the Exhaust

[VizioVHollow]

Hello! I'm having an issue with my Stinger where I've replaced the factory primary downpipes with catless ones and I noticed that oil is leaking through my exhaust. I took it to an exhaust shop to have some resonators welded on (catless downpipes are very raspy) and noticed there's a layer of oil coating the inside, as well as the car is blowing smoke while driving. A friend of mine who owns a Stinger and who's car is also catless told me that it's most likely because I didn't replace the gaskets when putting the new pipes on. I just wanted to get some other opinions on what could be causing this. Any help is appreciated! Just some background, it was not smoking or leaking oil before the downpipes, there's no CEL, no change in drivability, or anything other adverse effects.

Has happened to several people who replaced primary downpipes with catless. This shouldn't come as a surprise - it's been talked about a bunch.

I haven't seen any discussions regarding this since I am new to this forum. Have any fix actions been posted? Thanks for the reply.

Oil is leaking out of the turbos. You need to change your tune to account for the primary pipes.
