Has anyone seen or had this before? About a week ago I noticed a burning smell coming from under the car, it was strong enough to smell just standing next to the car. I thought maybe a plastic bag or something has got caught on the passenger side cat. I saw 2 large burnt areas on the cat itself. I cleaned it off with a wire brush and the next day it was back. Cleaned it a second time and it's still coming back and smell is getting worse, like burning metal or plastic. In the pic below you can see the burnt spots I'm debating if I should take it in and try for warranty work or just upgrade to some magnaflows since the warranty is about to expire in 6 months. I have a 2016 RT no mods other than adding the Mopar exhaust last year.
