Just in case anyone wanted to know... On my H30 I was able to remove the old muffler and thread in a 1/2 inch pipe nipple and 2 45s to make my header/ muffler. I bought all the stuff from lowes. just by the seat of my pants, it seams like it has more torq....
I used 2 inch threaded out of the head,had to use 2 45s and a 2 inch piece to bring it up a little and a 6 in long to a 1/2 to 3/4 coupler to a BS muffler with 3/4 threads on it. not as quiet as I wanted but it works great.
