My oh my. What a great sound it makes. Haven't calibrated the ol' "butt dyno" but feels quicker up top from 5500RPM up. While I had it in my friend's shop, I put it on the lift to see what the aero package consists of. It's not at all what I thought. I thought the underside would be flat but there are 5 panels under there. One crosses the sub structure behind the tranny. There is one on each side by the cats, one in the rear, and another in front of the rear muffler. They look more like flat pieces of plastic with scalloping on the edges. The one in front of the rear muffler looks like an upsidedown wing.
