sorry for the late response time. I've kind of been away from the thread. I'd be glad to get together some time. Since I have posted this though, I have not noticed much noise. It kind of comes and goes and that's why I was leaning towards tire harmonics. Of course I'm running a Magnaflow system and it's hard to hear minor noises. But you have to be on the interstate doing around 70 to hear mine.ScottsGT, I see u live in the same city as me. Can we get together this week and we can ride in each other's cars? I can probably tell u if it's the tires or something else. And you can ride in mine and hear the vibration. I've about given up on this car. Going back to buying old used cars, much less problems and cheaper.
