don't know for sure how much , but you would feel a difference. Do know that it will be worth you getting a remap eg ECUTEK3 to take full advantage. You should be seeing 300+ then

With the full PPP exhaust and a good re-map, you could be looking at 320-330 The exhaust alone would possibly give you maybe 270-280? It's a good enough system but you should look to the ECU to take full advantage.

i have allmost the same set up on my "MY05 STI" apart from green filter and tsl group n back box....its since been mapped with 318bhp/314 lb's running on 97 ron fuel.before it was mapped with the bits fitted i did not notice much gain in power so imho you really need a remap.not only did the car feel a lot faster after the mapping its miles nicer to drive with the extra torque.

You will need to uprate the fuel pump, then 330/340 bhp and 310/320 ft lbs given you run V-Power fuel. car would/should be comfortable at that.
