3" downpipe + 2.5" catback= boostcreep?

[speedy13]

I recently purchased a Megan 3" downpipe.I have a 2.5" catback.Would i have to worry about boost creep or should i be fine?I will be cutting off the extrapiping and using a stock cat(I live in comunist cali).Should i get a 2g o2 sensor housing?,port my 1g?or get a 2g one and port it?All advise is greatly apreciated.

only one way to find out

but in all honesty i haven't read one thing on this board since joining, that people had problems with a 14b creeping on them. I'm not saying that it doesn't happen, or that people havnen't documented it, but mostly I associate boost creep with the 16g turbos.
