UPDATED 10/22/18 I tried TWO of these mufflers when they rotted on me. The outer casing is not stainless steel and will rust quickly. I bought it hoping the stainless steel construction would make it last longer, but it didn't. The OEM muffler lasted from 2001 to 2013 and this part will not last more than 3 years. VERY DISAPPOINTED. The sound of my wife's car has changed a lot. Very quiet silencer. Stainless steel is a big plus for any exhaust system.
