What Mods void warranty?

[Toasty]

I've personally seen and changed 2 sets of head gaskets on L36's one in a 98 bonne and a 99 gp gt that were eaten away by dex cool thats what makes me hate it from experience and seeing what it does. And on the gp gt it had to have a near rear head. as well

---- but i thought it ate the heads, not the gaskets???
