I took my car to the dealer today for service because I would hear a vibration coming from the dash board area. The dealer called me today saying it was because i removed the secondary cats. Has anyone that removed secondary cats heard any vibration at idle or when the car is stopped?

absolutely especially if you do a catback exhaust...you will hear more vibration noises...I had to stuff my ashtray and cupholder in the rear seats with a small rag to reduce the vibration coming from the inner parts..It worked wonders and I get the occassional vibration once in a while in my armrest console compartment...Can't keep any loose change in there whatsover because the coins rattle!!!!

I have a down-pipe back exhaust with the 2nd cats gone and no vibrations.

Only "rattling" is from the rear center console lid which I just stuffed with some terry cloth and the rattle ceased.

The vibration i am experiencing seems to come from the driver side front area of the dashboard. It only happens when im at a stop once the car starts to move it goes away. Is this what you experience or does your vibration continue after the car is moving again?

LOL I'm having the same problem right after the installation of my quads exhaust.

For me its worse on a cold start, but once warmed up, no extra vibration at all.

I have catless DP's and I feel vibrations from time to time, esp during startup and idle at stop lights, nothing rattles though..

Its not a rattle but vibration like zzzzz noise....Its not always there but during the times when the car is still warming and the exhaust hasn't reached it optimal temps yet!!
