A**N
Do NOT apply on your exhaust flanges
My heart is still pounding as I was rushing in all directions trying to get something to extinguish the fire with. I applied this RTV on the collector flange, downstream the headers, to arrest a leak and correct the AFR reading on the wideband. I saw some smoke, and I thought maybe it's the high temp paint on the header. Next I saw flames, and you know the rest. Beware, for your own safety!
