Default My 08 Vibrates at 80mph.
Hey I have a 08 V6 and when I hit 3000rpms and 78mph there is a loud vibration. It goes away around 84mph. Anyone else have this problem or an idea as to what it might be?

does it have something to do with your exhaust?

i would get under the car and inspect the entire system, shake everything to make sure its solid. inspect the rubber hangers & mounts for any cracking, and check that everything has plenty of clearance.
