Welcome to the SS Forums @Blue2018ss !!inhave 2018 ss with 6.2l that has a 2.9l whipple it also has a horrible rattle sound at idle only. I spoke to whipple charger sales/service and he sent me out a coupling kit saying that would fix the noise but it did not and honestly it’s pretty f'ing annoying to me I’mready to rip it off and go back to stock
