[Lithias]

Updating from my morning drive. Squeak was barely audible, I did notice significant buildup in the exhaust pipe and on the valves themselves, like pitch black, so I'll be spraying them down tonight and giving them a good clean as safely as possible.

The squeak is only when the valve closes and does not squeak when opening, completely the opposite of my original problem with the first exhaust.

I could not hear anything with the windows down and driving, however it was audible when parked, but not any worse than with the windows up.

Will clean tonight and update again.
