I looked at there website and the wastegate they offer is a off-brand wastegate, not a Tial wastegate. It is not to say that their's does not work, but i a certain there is a difference in quality. A Tial wastegate alone is $369.
Someone on the board just sold a 3" stainless downpipe for $390, so i feel as though my pricing is not too far off what is fair.
Again this is all brand new stuff, never been mounted before.
