I'm selling the LM. Took it off Tuesday. A buddy of mine and I are thinking about ordering a 3" intermediate pipe (dynomax maybe) and running a single 3" in/out muffler with a 3" single tail (ala mufflex). What I'm wondering is what the difference would be between a 30 series and say, a 50 series. Also, does anyone know what series muffler they use on the mufflex design? Is it a "Top ten series flow " race muff? I'm trying to go for a very deep sound and not worried about the lower sound level (I'm running macs/ORP anyway). I've decided to scrap the true dual idea since I don't want the headache of testing/adjusting this and that. TIA.
