GT28RS Turbo Piping ???

[sillycar09]

Next month , I will start my project !
I will install GT28RS with 38mm Tial Wastegate (MWR) 7psi (0.5bar)soon..
The piping Is It necessary need to resize to make it bigger which is 2.5" ?? Bc now my whole piping is just 2"...
Some people told me If low boost , 0.5bar is doesn't matter..stay with 2"..
If boost around 0.7-1 bar then better change to 2.5" or 3" ??Is It true ??
Wait your guys reply ! Thanks !!

what are you using for management. when you change the diameter of the tube the MAF is in, it alters the calibration. with what you are planning on doing, i suggest staying with the same diameter as stock 2.75

as stock 2.75
Note -- outside diameter is 2.75", inside is 2.5"

But yes, this is good advice.
