Recently installed Evolve lowering springs + EST exhaust (plus IPD stage 2). Now when I start out in first and sometimes after shifting to second I get this creaking / moaning sound that sounds and feels like it's happening immediately below driver floor. I plan to take it to shop to see if they can figure this out but thought I'd ask if anyone has had similar experience. I searched other posts re creaking sounds but they seemed to involve only sway bars and hard steering wheel turns. Thanks.
