how large of piping do most of you go on your exhaust with the turbo motors? i was considering redoing my exhaust with 2.25 piping but wasn't sure if was big enough with my plans to bring some Forced Induction into the whole shibang..

 

most people use 3" for turbo. but anything larger than stock is an inprovement. 2.5" is a good balance between na and turbo if your not going to turbo soon.

 

 

3 inch exhuast, DO IT NOW, especially for turbo no turbo then stick with your puny piping till you get the turbo.

 

It would depend on the displacement, turbo,and turbo boost"PSI" you are using. No smaller than 3" pipe recomended.
