what is a good route to go down and whats it going to cost?

would be more than happy to reach some where between 320-340bhp

any help would be appreciated

No need to change your up-pipe only the WRX's have a cat in the up-pipe and the one fitted to your car is perfectly adequate so keep it and save yourself £100.

Sports cat downpipe, centre cat delete pipe. Remove front silencer replace with straight through pipe and change standard back box for one of your choice. Walbro fuel pump and panel filter and some NGK -7 plugs.

Andy Forest remap ( a must) and away you go - sorted. Well to start with
