After L warms up for a couple of minutes, there is a rattle right at muffler, at various different RPM's. sounds like the heat shield (all muffler clamps are tight). anyone have this problem ? how did you fix it ? i suppose i have to drop the exhaust, but i wanted to know if this is the problem first. don't want to go to the dealer if i don't have to.

 

Try having someone sit in the passenger seat. If the rattle gets worse, I know the solution.

I presume this solved your problem want-a-L?

 

yeah, thank god you gave me that, the dealer kept trying to adjust the tail pipes and not the muffler

I've been wondering what the hell that noise was, I called it the three person noise. The dealer tried to fix it and told me it might be the transmission. This site rules!!!!
