    Loud Mouth or Loud MouthII

    I'm looking to get a catback system for my mostly stock 94Z A4. Was going to get the original loudmouth but then heard of the loudmouthII system. How does the two differ in loudness or sound, has anybody heard the LM2? If i put either of these on will i increase or decrease my MPG?

    My friend actually has LM II on his 05 Stang GT and it is pretty quiet.. Quiet at idle and nice when hes on the gas. No where near as loud as the original LM which can be obnoxious in comparison..

    Also the reg LM can be VERY raspy and tinny and somepeople dont like that so as Fase2Black & ZBONER said check out www.ls1sounds.com and hear for yourself...

    I have the LM on my car. It sounds bad-ass from the outside but at highway speeds, I have to stay away from cruising at 1700 to 2000 rpm's. The in car rasp is extremly annoying and almost ricey sounding in those rpm's. LMII fixed this I think.
