Im going down the same route apart from the up pipe as that can mess with the spooling of the turbo depends on what make the up pipe is tho i have 3 inch cat back was thinking about 3 inch decat down pipe might need to be remapped tho

i will just be running an STi up pipe, Prodrive sportcat down pipe and a H&S 2.5" system....
one cat in the system..... good for 350BHP anyway.
your 5 speed box wont cope with much more than 330lbs/ft anyway.
Hope thats of some help.
PS. remap is best after this, although I believe that with a sport cat the car would still be ok to drive, just not at its best.

you wont see anywhere near 350 bhp with just those mods.. if your car isnt an sti. if its a wrx you will need a bigger turbo vf34/35 ect bigger injectors pink 550s sti top mount intercooler ,walbro fuel pump,full decat exhaust and remap..oh you will also need something to stop the bugger too

my answer was that this exhaust system will run 350BHP with the supporting mods, which the OP hadnt suggested he had therefore the system I proposed would be more that enough to cope with his needs.

However not knowing or implying what the guy drives like I was erring on the side of caution and what is generally accepted to be the g/box limits for reasonable reliability.
