The first one sounded the best for sure. The loudmouth 2 has kind of a, I don't know, italian super car kind of sound. Higher pitched for sure. Definitely sounds better than other videos we've seen. Now it can only beat GMPP for price and power, I think I found my new exhaust. GM better get some video out of their exhaust soon to compare before people make their minds up.
