HELP?!?! Whats this mean?

Tubular o2 housing with tial 40mm mounted onto the stainless steel o2 housing.$250 .....................is that an external waste gate or just one a half assed extermal waste gate mounted after the stock waste gate? and would that be a good buy, how much would you pay

used ? a tial alone cost alot more then that.
If you kept your internaly gated turbo .. then yes it could be another gate
after the internal one.

what if you ditched the internal by removing the flapper? would that get rid of boost creep yeah te tail 40mm is like 300 something i think
