How many miles do the turbos normally last? If they are easy to replace (just a few tools and a lift) i'll do it with the exhaust system overhaul.
They are expensive to replace (factory wise) so you're not going to want to do it when you do the exhuast.
I've seen turbos go out before the warranty expired and I've seen some last over 100k miles. Maintaince (oil changes and such) are important to a turbos life.
