Looking to upgrade the factory exhaust, just bought an 04 A6 and so I don't have a ton of cash to play with, just want to prolong turbo life and get some better flow any suggestions?

 

I posted this question along with another one around a week ago with almost 200 people looking at them with no response from anyone. Did I post in the wrong place or something? Never had an experienced like this on any other car Forum.
