Hello everyone, this is my first time posting on here and I apologize if this is the incorrect forum or place to be putting this. I just recently got a 2018 sti and every time I’m in 1st or second gear and start accelerating WOT after about 3k RPMs I hear this really loud rattle sound. It sounds like it’s somewhere under the car towards the back or center. Very hard to pinpoint it. I can’t replicate the rattle in any other gear besides 1 and 2. Please help ? Its freaking me out
