Downpipes with external wastegates are optional, that's what you are seeing on the pics, you can vent them to atmosphere (illegal) or you can recirc back to exhaust. They are $1k+. You can get 3" testpipes instead for less than $400.

If it's within budget I would upgrade exhaust, it does not have to be a 3" though. HKS Turbo Ti is 2.75" and even a nice flowing 2.5" will do
