I hit a bump in the road. I looked underneath my car and near the front of my car there is something that looks like a wire mesh. It also looks like it is connected in someway to the exhaust system. What is that? Is it easy to replace. After I hit the bump I didn't notice any different in driven like any noise or shaking. The wire mesh just seems to be torn apart a little.

It's just a mesh that covers the front exhaust pipe. Why it's there, I don't know but we remove them all of the time at work.

He's talking about the flex pipe.

Unless you hear your exhaust more then before you'll be ok, but keep an eye on it.

THat's not exactly the same type of mesh. It's actually a braided stainless steel wire covering that add's strength to the flex joint while still allowing it to "flex." It compensates for the back and forth movement of the transversly mounted engine under torque. Without the flex joint, a solid exhaust pipe would be stressed under the same conditions.
