another 996 plenum and tb question

[Paseb]

Ok guys,

i have another question regarding the 996 plenum and tb question

i currently have a 996 c4 3.6l 996 plenum and tb in my shop.

current size is 74mm,

is it a direct bolt-on to a stock 3.2l motor?

or i need to buy reducers hoses?

would you invest more and go to a 76mm size?

im currently running straight pipe, except i still have the stock headers(cats)

has anyone been running a bigger straight pipe system?

i cant remember the size of the stock piping but, would there be any benefice to go to 1.5in instead of 1in? numbers for reference only

thanks
