Muffler magician!
When it comes to exhaust, you need to go here. I found The Muffler Guy in Newmarket through a google search. Brought my 2008 Honda Pilot for what was diagnosed as a "exhaust flex joint" rattle. Within minutes of inspection Ken, the owner, came out and informed me it wasn't the exhaust at all, but a loose heat shield. Two clamps later the rattle was gone! Despite a less than welcoming foyer, the Personal service, appointment promptness, and work done properly is why you need to go here.
