Hey all, I have been cruising the forum for a while and thought that I would post and get the opinions of those who have a bit more experience modding Subies than I do. As the title says I am looking to get 315 WHP and after doing some research and talking with the tuners at a local shop I have my plan, but wanted to get some insight from anyone willing to comment with any experiences they may have. I have a 2013 WRX wagon with an Invidia Q300 exhaust (Mid pipe back), I was thinking based on what I have read that if I go with a cold air intake (Cobb), Invidia High Flow Catted downpipe and an open source tune that I should be able to hit this mark pretty easy. The shop I spoke with suggested adding a Tomioka uppipe into the mix, but I am not sure if that's necessary. I would love to hear some ideas from everyone based on what they are running. Thanks in advance!!!
