2001 honda prelued oil leak for exaust?

ok i took my 2001 honda prelude in to get a few thing done last week i got the oil changed and on the way home i smelled brunt oil thought it was just a lil spit on the engine but when i got hom i popped the hood and say a good bit come out. i crawled under and saw what looks like a braied line type thing that come from the down pipe and goes to another pip and into the cat (looks like a chines finger trap but about 2 inches in dimater) and the smoke was comeing from it so i got oil leaking some wear in m y engin and going in to my exaust. i read it was eater a o ring or something to do with my valaves not sealed right what should i do i was thinking on some stp oil stop leek for now till i can have it looked at next payday
