How did you run your exhaust out the back?

I need some pics of how people have run dual exhaust and how they exit out the back. I am going to get 2-1/2" pipe run to headers and have some concerns about sucking exhaust back into the truck. The shop that is going to do it says anytime he does a Blazer, Tahoe or Suburban he has problems with people complaining about the exhaust smell when he runs them straight out the back. I have also experienced this and don't want to deal with it. That is what I had planned to do, so now I may angle them down and out a little in the coners of the back of the truck. Just wanted to see some pictures of different options. Thanks
