I checked with Fister & they have not done any Stage 1 or 2 work on a set of GHL Mufflers. Wondering if anyone else on the board has done the LPMM/Fister Stage 1 or 2 to a set of GHL's?

They are already a litte louder than stock, but have some resonance b/w 2700-3000 rpm. Just wondering what they might sound like moded & if the resonance will go away?

The other thought would be to sell them or swap them for a stock set, then let Darin go to work on those.

We had an LPMM with our GHL. We went to a local muffler shop and they did the LPMM mods for us. I still have a sound clip if you want to hear it.

Thanks JoAnne, that would be great. What did you think of the sound after the mod? Did it get rid of the resonance b/w 2700-3000?
