I just got done putting in my ga15, well mostly. I haven't put in the axles yet because I want to replace the boots first. It sounds awesome, BUT it makes this REALLY loud squeling or whisling nosie. I mean it's really loud, it causese me physical pain. I have no I dea what it is. it's not any belts and it's not any accessory(p/s, alt, or water) it sounds like it's coming from the intake side but I can't be sure, I have bad hearing. I really need help with this.
