headers turning red while driving hard with race gas
I was running a few friends corvettes and they all kept seeing my headers/exhaust turn bright red with the occasional flame coming out.

I am running a tiptronic 996 with alpha 28's and no cats with 105 octane unleaded fuel at 1.6 bar

I had my tuner look at a pump gas tune and it was perfect, guess i need to send scott my race data logs?

I was beating everyone, but lost to the c6z with a blower and methanol

You can see the bright red headers at around 2 minutes followed by a flame

Run a car hard enough, headers will glow regardless of whether or not you're using race gas. I assume the flames were coming from the exhaust tips (and not from UNDER the car). Combustion of unburned fuel, not surprising without cats.

Your exhaust is holding up well on my car. So are the agency headers.

No 6speed. But that doesn't matter as far as exhaust goes.
You still on one fuel pump? If so consider putting in another one.

Sounds normal to me, my car shoots flames about a foot far everytime I snap gears during WOT.
