aftermarket muffler that will fit a thunderheader head pipe??????

[hotbagger1]

I want to keep my thunderheader  head pipe but want a different muffler,  does anyone know what will fit?

You can always buy a muffler you like, then make it fit your header pipe. If he header pipe is too small, a pipe expander will stretch it open a bit. Same deal if the new muffler is too tight for the pipe, stretch it open. You can get a set at HF on the cheap.,,,

Check with Jeg's or Summit for Super Trapp mufflers, guys have used them in the past with success. They come with all sorts of exhaust tube sizes and can be tuned with the discs. Available in different diameters too. fwiw Buffalo
