what power/tourqe will this set up make approx on a my05 uk sti

prodrive 1st cat
2.75" milltek from 1st cat
k&n panel filter
3port boost solinoid
ported/wrapped oe manifold
up-pipe????
walbro fuel pump
powerstation remap

any other bolt-ons worth adding?

 

Depends what the mapper does with it.

 

put it on the rollers and find out

 

why change your up pipe there is no cat in it

 

this is the list of mods i will be fitting before my car is mapped and was just wondering what sort of figures i should expect.

im not sure on up-pipes, i know there is no cat in there but dont know if the stock one is restrictive or not.
