From looking at his site... it looks like he does the LPMM w/ minor mods on the inside of the II's and a major gut job on the the III's with no LPMM

Back in the day, another rennlister (Leland Pate) and I were looking into ways to modify our mufflers (not together, just around the same time.) RUF had a mod out that had a bypass pipe with the inlet and outlet connected together with a valve in the middle. Leland built one , minus the valve, with 1 1/2" galv pipe from the hardware store that he welded with mild steel. After he built his, I built mine with 2" stainless pipe and welded it with stainless.
This became the Fister Stage I muffler.
Stage II is a Stage I with internal modifications as well, TIG welded back together, giving it a different tone and volume level (more of what I was looking for.)
Then I went to the races in '08 and heard the GT3 cup cars, I just knew that was what I wanted to try and reproduce. After a few prototypes, the Stage III was born. It is a completely repiped (internally). It weighs in at right around 10 lbs and makes me smile everytime I fire up my 993.
