Ok, so I start my '03 up and it does have the Roush side-pipe exhaust on it. When I have it in any gear, it buzzes when I accelerate; however it does not buzz when i rev it in neutral. I have had the exhaust off the car but i put it back on and tightened everything. Any thoughts?

If you are hearing the "buzz" from inside the car while driving, chances are that something INSIDE the car is loose and buzzing. Mine does this from time to time as well.

Yea mine had the same problem. It was coming only from certain rpms?? Che k your e-brake button. While accelerating just hold the ebrake button to see if that's it. That's what mine was.

I checked the E Brake and everything but its fine. I think it is something in the transmission because when i have the clutch in and rev it (i know its bad but it was for a test) I don't hear it. It also does not buzz in neutral. But when I'm riding say through a work zone when the exhaust is hitting off the walls, I can hear the buzz clearly.
