i am planning on getting a low boost turbo around 6lbs boost and was wondering since its low boost i should get a 3inch or 2.5inch exhaust. Right now i have a 3inch megan turbo muffler with the adapter to smaller piping and if i got the turbo make it a 3inch full exhaust so 2.5 or 3?

If it's a proper, mandrel bent 2.5" piping into a 3" muffler, you will be fine. At that level, the money could be spent in other areas. Just avoid bottle necks in the system, make sure it's 2.5" from the turbo and never goes smaller. (i.e. catalytic converter)
