I recommend the loudmouth...@ $320, stainless steel, by far the easiest exhaust to install, and great sound. Up to 2000 rpm's it sounds like any other aftermarket exhaust. Once you open her up it is a whole different story, a real head turner! I have received many compliments on how "thoaty" the exhaust is. One people actually told me it was the best V8 sound he ever heard ! I have headers, which only made the sound better. If you want a mean sounding exhaust...go with the LM!
