Evenin gents.

This is probs going to be very easy for people to answer on here.

Im looking to get my Hawk STi up to the 350 BHp mark, the car is totally standard apart from the Prodrive Oval backbox I fitted 3 weeks ago, dont know if it is placebo but im sure I felt some amount of torque increase...anyway.. to get to the magic 350.. would all I need to do is remove the 2nd cat + resonator/panel filter and remap?

Will I present myself with any reliability issues with the power at this level on std internals or should it be fairly comfortable?

Attached is the current graph before I got the Prodrive back box.

 

your hawk sti will comfortably take 350bhp and reliability shouldn't be effected at that level
if it will make your target with those mods not sure but wont be far off.
sure some one will be on soon to tell you what power they will definitively make

 

Cheers.
