What gasket do I buy? 2015 RAV4 LE FWD
One of my connections in my exhaust is shot and I need a new gasket for it but I can't figure out which one. I found this diagram of my car exhaust system and it's the connection from the front pipe to the intermediate pipe. It lists 2 seperate parts for the same part# to the diagram. It shows part "Exhaust Pipe To Manifold Gasket 90917-A6002" and part "Exhaust Pipe Flange Gasket 90917-A6003". I bought the A6003 one but it doesn't seem thick enough to make the seal. I have a 2015 Toyota RAV4 LE FWD. Should I have bought the A6002 instead or was I supposed to have both for it? Or are my pipe flanges just messed up from rust that is causing the problem?
Edit: could I also just double up the gasket I did buy to make the seal? Other than the gap it is a perfect fit. Edit2: added comment with website links I was using for reference
