Hello all. I was just curious about the difference between LPMM and Fister stage I, II, III exhaust. I have the LPMM mod done on my 95 993 but am looking for more. It is hard to tell the differences online. I was wondering if some one could describe the differences to me. They all sound cool in their own way but I 'm looking for LOUD!! Don't get me wrong, this is not a contest to see which is better. Just louder.TIA Cheers!!

Fister Stage I = LPMM
The difference being all Fister Stage Is were made the same: 2" stainless pipe, holes cut to proper size for pipe, welded with stainless. LPMM was done by others with different sizes of pipe, different size holes, sometimes different materials. So some LPMMs may sound a little different than my Stage Is.

Stage II is a Stage I that is then cut open and modified, and then TIG welded back together. Again all in stainless. It changes the tone of the mufflers, to make them a little more aggressive. There is a volume increase as well. No resonance in the cabin.

Stage III is the most aggressive and lightest muffler I make. All internally modified with new stainless steel. No external modifications at all. Again louder than Stage II and more aggressive. Also no drone or resonance.

I hope that helps.

Thank you for your reply. Me thinks its time to start saving for some stage IIIs.
