I am lookin at this Audi on craigslist. The seller claims the only things it needs is a flex pipe. The motor is a swap from an S4 Audi, so its the 2.7 Turbo. I was wondering if this is an expensive repair for these vehicles. The exact price of the piece would be much appreciated. Is it hard to reach? would it be expensive for a shop to replace? I simply do not know enough about these vehicles and dont want to get screwed on craigslist, AGAIN (long story short). Any advice/comments are much appreciated!

Thanks guys,

Dave
