Eeeek... There's no way to not break through the casting? I was wondering if the gains of taking out the hump are actually worth it. I don't wanna get the northstar cuz I don't wanna open it up that much. Basically what I want to do so far is do basic mods at this point. I ordered a 2.5" dp with cat, overkill pcm, and made my own intake (which looks awesome by the way) haha. Do you guys know how much hp gain you can actually get from that typical setup?
