Exhaust Rattle

12-31-2005, 07:45 AM
Does anyone know a way to eliminate the rattling from the Cat shields on the exhaust. I've tried putting sheet metal screws through the openings on each end of the shields but they still don't stop the buzzing. Some have recommended just taking off the shields, but they must be there for some good reason? Any suggestions, the noise is driving me nuts. (It mostly happens at idle)

I have removed the exhaust shields on my M and have had no problems at all.
