I use real silver soldier with a melting point just at dull red on the steel so im sure this isnt gonna come apart, if the muffler gets red ill need more than a new muffler. a aluminum muffler would melt at the same temp as this soldier does. silver works so much better than braze because it flows like lead does when u use the rite flux at the rite temp. i havent run it yet so im not to sure about the outlet pipe. we have a noise limit at the field so i maybe stuck with this size pipe outlet pipe. i will try different size just to see tho. i can cut off the reduced end and have a larger dia outlet. the nice thing about this fabrication is the size and weight. so far i dont know about the noise and power effects. its only 1/3 the size it was when i started
