Strange red glow under car

[attym3]

I was just following this Mazda and there was a red glow under the car. I don't think it was boy racer neons as it was only on one spot and right in the middle of the car. I got this pic but it was on my iCrap so it's not the best.
Any ideas?

Something wrapped around the 'zorst starting to burn?

Did it sound otherwise healthy?

If it had been running with a misfire, then the catalyst could well be running a little bit on the warm side?

Was it on fire?.

Just a thought - don't speedometer calibration devices use a laser on the road, similar to an optical mouse? I'd agree with others that its likely a DPF or cat running hot.

If you look just under the num plate you can just see it reflecting off the road(just)

I reckon the catalytic converter. I have seen pictures of these glowing red on RX8s when the cat is starting to fail; basically the honeycomb structure has deteriorated and collapsed, causing a blockage.

Yes, and if you put a bit of tape over it the speedo stops working

It can't be easy to drive and use your mobile to take a picture at the same time ...
