My 09 Odyssey has 190k on it. Recently, when I turn on the car, the engine sounds normal until it warms up. As it warms up, the engine gets progressively louder and louder. I’ve never heard this before. I have an appointment at the dealership tomorrow, but I don’t want to pay whatever huge bill they come up with. Any suggestions or thoughts as to what it could be?
Check all the pertinent fluid levels of course, but it’s probably an exhaust noise, maybe you got a hole in your muffler that is opening up wider as it heats up.
Cracked exhaust manifolds usually make a lot more noise when they are warmed up. If you don’t want to pay dealer prices, why are you taking your car to a dealer. Find a good local shop.

After the problem is diagnosed you can shop around for price, how much is having a quiet vehicle worth?
