Please help idenitify this part undercarriage

I wouldn't let that worry me. Or go to the dealer and they'll walk you through getting one I don't think the aftermarket exhaust people would have it

 

It’s the Front No. 3 Engine Under Cover, part number 51442-12210, secured by four clips, part number 90467-07214.

Parts catalog reference: Figure 51-02, Suspension Crossmember & Under Cover.

 

I think it may be also made out of foil and that fireproof material it's not real it's like a stick could rip it off the car similar to the thing that sits forward of it that's just above made of plastic mine's sitting here on the ground laying here been here for some time as my 13 also has the rock trays out underneath the front and rear floors on each side of the car. They were filled with 63 lb of gravel when I pull them down they were hanging down like cow utters. So by taking those plastic trays down I lost quite a bit of weight immediately and now they're not there to fill back up and the car hasn't really lost any gas mileage.

 

I too did Flex and also sent my '15 down a gravel road haha The part posted by @Elektroingenieur is the correct part.

 

The site Mendel always quotes will have lowest price I bet . But I would think nothing of leaving that off like the under trays that are off my 13 right now they're laying in the carport never to go back in I don't imagine
