That pinhole in the pipe is there to let condensation drain out. Don't fret, we've all got one as standard fitmentDid a smoke test to see if there are any leaks both under the hood and along the exhaust. Found a small leak from the exhaust manifold (probably a gasket). I’ll have it replaced next service since it’s not a big deal.
What surprised me was the leak from the brand new exhaust back box that my dealer replaced a month ago. Guess it’s time for a new back box…..again
