Water in Mufflers 2017 C63s Sedan
 

I picked up a new leftover 2017 c63s in August of 2018. The car did not have the valved performance exhaust so I just changed it out for an AWE Switchpath...the car has 5,000 miles on it (really enjoying it thus far). I was surprised at how much water is trapped inside both the stock mufflers and is sloshing around. It sounds like a quart or more in both mufflers. I didn't notice any type of drain and it's not coming out. Is this normal?

Sounds like someone got a bit too happy with the hose when washing the car...

Drive it out! It should burn off/exit the exhaust just fine.

Noticed the same thing when I had my AWE track installed. Stock rear mufflers had lots of water in them, and you can't get the water to drip out.
