    uhmmmmm.. after reading your post, I have to ask.... you do realise that whether you have the stock silencer (steel) or aftermarket (aluminum) that to generate enough heat for it to glow red, your entire piston would be a molten slab of aluminum in the bottom of the case......... what you are stating is PHYSICALY IMPOSSIBLE.

    thats the headpipe on a 4 stroke... stretch a blaster pipe out, thats what 3 feet at least of exhaust... untill you get to the silencer...
