Default oil leak

so the car has been running great. til about 2 weeks ago i noticed one night there was a 6" puddle of oil on the garage floor. I looked all around the engine compartment but didnt find any signs of where it was comming from. Got an oil change and driven with no problems. this evening when pulling into my garage. I noticed the puddle is back. so i look from the top of the engine and i dont see any leak points. I crawl under the car and im seeing a piece of the undercarriage plastic cover back by the exhaust(where the headers meet the midpipe) and that is where the oil is dripping from. I know there are a few different places that plastic cover could be accumulating oil from...but where is the most common?

thanks for the help.
