2g exhaust question

[mistagst]

so i have a 2.5" new ported o2 housing and a downpipe that starts 2.5" the extends to 3" i have a 3" testpipe and a 3" catback. my question is...is there going to be enough back pressure for my t25? only other mod is a injen intake with k&n filter. i will be getting a nxs boost controller and boost gauge soon. i want to know if this will work before i put it all on
