popping exhaust video
I know this has been discussed before....but this is my exhaust during a cold start. It sounds more obvious in person....but is this the same sound that everyone else has been noticing? :confused:

Yes, I hear that popping as well. Additionally there is a "knocking" sound - coming from under the hood I hear when I do a "hot" start. After the engine is nice and hot, let it sit for 2.5 hours and then start it listening up front. You may or may not hear a "knocking" sound.

Sounds pretty good...and pretty normal to me. I admit it does seem to have a touch more "aftermarket exhaust" sound than mine, but I only have 3K so far. I wouldn't worry about it unless you get a noticeable engine misfire which can cause big pops as the raw fuel hits the catylist...but not on a cold start.

My C350 sounds really quiet compared to that... however, I am always inside of the car when i start it up...

Sounds normal IMO.

Rick Also, I didnt notice my exhaust was making this noise until I saw a thread about it on here, and checked it out. But hey, I think it sounds pretty cool haha. |

I think it's normal for these V6's.

Yeah, I hear that knocking sound too on a warm start....it doesn't occur all the time though. My dad's ML350 does it too. I think it's normal for these V6's.
