Up for sale are both external Gredy External Wastegates that are sold in their TD06-20G kits for the vq motors.
Included in the price are both wastegates and their stainless steel pipes and dump-tubes.
Asking price is $300 shipped for both of them. I think that is a fair price for them. :dunno:
Pictures are below as well as the factory picture from Greddy of them installed.
