Is this normal? Oil on exhaust tips
Only mods are rpi scoops and an akra slip on. after driving a bit spiritedly I noticed oil on each of my exhaust tips. after cleaning up the tips a bit I noticed that it was a good amount of straight oil and not just carbon buildup. No CEL and the car is behaving normally. Does this happen for anyone else? Is it a reason to go to the dealer? Thanks (sorry for the large pics)

that looks like water on a dirty tip to me. Its also on the sides.. oil wouldnt just find its way up the side of the tip like that.

If that is oil then you have a big problem. Do you know how much oil you are consuming currently? It could be an issue with a piston ring (worst case). It may be a bad exhaust valve seal. I would get the car checked out as soon as possible.

I don't think oil would ever make it through the cats unless the engine was dumping it like crazy lol. Probably just water.

OP - There is definitely something wrong with your exhaust. Pack it up and send it to me for testing, I'll let you know the results in a few months.

+1 I would clean the exhaust really well... then try to absorb some of the liquid on a rag and see if it is in fact oil or water. i think the latter

i highly doubt it was water but I could be wrong. I cleaned it off with my fingers and definitely felt and looked like oil. I'm burning through about a quart every 4-5k. It hasn't happened again since that day and I cleaned up the tips to see what comes back

If it was oil it would never fully dry. I say soot + condensation.

For an engine to push sufficient oil through the exhaust valves, down the headers, through the cat and silencers to arrive at the tips you would be using a qrt every 10 miles - but way before that you would be getting a dash full of warning lights about emission failures and clouds of blue smoke when the engine was running.
