I've heard the metal tube will give more whistle than the plastic tube. Anyone have an AFE Stage 2 metal tube for an LB7?

I had both and the new plastic one seems just as loud , I found no real difference. JMHO

For more noise, you need to Bend a Custom Alum or Stainless, 6" or 7" stuff, with a neck down for the filter.
