Exhaust Issue: C43 sounds like a Mustang GT
Looking for any suggestions here. Turned off the car the other night after a short trip and it was noticeably louder than normal as I shut it off.
The car now sounds like a Mustang running without mufflers. Sounds wicked, but not something I want to live with. I'm thinking I may have blown a cat?
Car is in solid condition, 145K miles.

A blown cat would have some pretty bad effects and would also throw a C.E.L.

Lensolo,
Thanks for the reply. No C.E.L. was thrown, and from a quick visual inspection, there is nothing out of the ordinary.
I thought it might be the cat due to the fact that the sound has a booming characteristic and seems to be coming from under the center of the car.
If it's only a muffler, I'll be very happy.
In my post, I noted 145K miles...it's actually 147.7K. Mostly highway, but still looks new and runs great!

I would have to guess a whole in the muffler somewhere, get it checked ASAP at a dealership before it gets worse...Great to know that a C43 is still running excellent at that kind of mileage!

Is it normal when starting a cold engine and there is a small water leak from the rear exhaust gasket? It happens in freezing temps. My dads 06 MB E350 does the same thing.
