Been awhile since I post here, but here we go. Went to do an oil change and noticed it seemed a little low. No engine lights or anything prior to this. Used an vacuum extractor and it didn't seem as full as usual, thought there might be an issue with it since the seal kept popping out. Go under the car and remove the panel, nothing out of the ordinary, and pull the drain plug and nothing comes out. Double check everything and nada, no oil. Put in the usual 6.5qt or so and start her up and no engine lights, everything sounds good, look under the car and there's a drip, all the way back on the right side exhaust where the catback connects to the secondary. I know people with catless/hi-flows on the primary have had issues but I don't have primaries. Any ideas on what's going on here?
