I am in the process of putting on a cat back and I am trying to save money while still doing it right. I am wanting to increase piping size. Does anyone have a 15+ WRX or STI catback laying around I could test fit? The only issue I can find is that the mid pipe will have to be shortened a few inches but that's no big deal. If it ends up fitting I will likely buy it if you are interested in selling it. Reply or pm me if you do!
