Hi guys

Let me introduce my car to you guys. I have 2017 Ecoboost Mustang with high-flow catted downpipe + catback, CAI, Intercooler. The car recently have raw gas smell coming from the turbo side. The car idle make "thumping" or "pounding" noise. I figured it out 15 mins ago after driving that my exhaust manifold is glowing red.

I wonder if any of you guys have any ideas what might be going on?

Thank you very much for your time and help.

Wrong section, this isn't for issues about your Mustang. It says right at the top of the section:

I would take that baby straight to my Ford dealer ASAP.

Moving to tech..

Did this happen after the mods were done to the car? Is there a difference in performance? Maybe a bad bearing in a turbo or something, no clue really.

Are you not getting a CEL? A red cat indicates (to me) that fuel is passing though a cylinder and into the cat, where it's ignited. Your ECU should be picking up a misfire.

Stuck injector, broken spark plug, bad coilpack....look for anything that's causing a cylinder to miss burning all, or any of its fuel.
