adding an aftermarket uppipe should let you run higher boost but not exceeding safe boost of the stock turbo itself. say 18psi?

Mine has been seeing 15psi peak boost pressure for over 25kmiles with 37k tot. miles on my car.. But Thank-god that thing is comin' out in two weeks! I'm looking forward to it..one less thing to worry about+increased performance. Anyway I think the answer to your question is not one that has an set answer, my car does not have (excessively)high EGTs, but whats to say that if it did my upipe cat would not have already disintegrated into my turbo? There are alot of variables is all I'm saying.
