When I got the 2011 last November with 44,000 miles, I noticed an odd noise like a high speed bearing going bad seemed to be coming from the passenger side. I've been keeping an eye on the hubs and the exhaust flex pipe, they seem fine.

This weekend I put the car up on stands and had my lovely assistant give it some gas while I was laying under it. Imagine my surprise when I noticed droplets of water coming from the flange between the cat and the resonator! Then I noticed an exceptional amount of rust on the flanges.

So a trip to Advance to get a new $4.99 gasket while WD40 was working some scraping with a brass brush and liberal anti-seize, and now the car sounds "normal" again.

 

success is a beautiful thing....
