God bless the SVA how hot do they think your exhaust gets??
Im assuming your not at the very start of the headers with your band/pop rivet.
I wonder if the Vehicle inspectorate ever stopped and wondered why paper thin alumium sandwich head and exhaust gaskets dont melt where they protrude into the flame path?
Dont forget to rivet in triplicate for them!!!
Melt temp Aluminum 1190 - 1215 degress C
