They will vibrate almost every time the rpm's are higher than about 3 or 4k. During acceleration from a stop light, it feels like when it starts to vibrate, thats the time to shift up a gear.
The vibration then stops when my rpm's decrease because I shifted up, but will then start to vibrate again as I speed up before shifting up again.
It sounds like the vibration noise is coming directly from the right muffler (maybe the left one too). The mufflers do have rusted spots where the metal completely fell out forming holes close to the opening of the muffler.
I've tried to shift the muffler around with my hand to see if its loose but seems pretty secure.
I cannot tell if its the engine causing the muffler to vibrate or if its something in the muffler thats loose..
