Default Please help identify this part

All

1999 Z-28 Stock

Here are some pictures of a valve that is on both sides of the engine. I can't seem to locate these in any parts catalog.

The one on the passenger side is totally discolored from heat and has a split. The other side is painted black and seems to be OK.

These are connected to the exhaust manifold directly on both sides and looks like a crossover. What do you think and what is the name of these guys?
