ATR external wastegate

[just plain john]

I have a used ATR downpipe that has an external gate. Is it worth rebuilding (Kirbans has the remaining ATR components) or is there a better alternative?

Better alternative is a TiAL Sport 38mm gate or one similar to it.

Maybe Patrick can confirm but the Precision would work well:
