my highlander check engine and VSC light came on about a week ago and just
in the last day or so the exhaust got a lot louder, what could be wrong?
You would need to scan for the codes to pinpoint the exact issue. But sounds like an exhaust leak to me, which would trip an Oxygen sensor code. Have your mechanic or muffler shop check it out.
