Coolant bypass?

 

[Shibby50]

Coolant bypass is correct. Drivers side would t into the coolant crossover and the passenger side goes to the radiator cap otherwise

Everyone that buys an f-body bypasses those coolant lines. All they do is heat the TB. I'd leave them as they are unless you are looking to turn the car back to 100% factory spec for some reason.

Coolant bypass?

The looped hose in this shot is not a coolant bypass. Looks like this was converted to LS6 PCV system.

Its an 04 gto with aftermarket valve covers.

Same with the LS1 GTOs your guy was just lazy didn't get the little covers for them.
