Guys, I need your help! I just bought an 07 rrs sc and it had a growling/metallic noise coming from under the drivers right foot area. Dealer told me it was the tranny mount which they included but after I replaced it sound seems worse. It's only in drive and not in reverse and only under load. Had a shop look at it and they confirmed the engine mounts are fine and could possibly be an exhaust pipe or heat shield. Has anyone ever heard of this? Please help!
