Oh is that it? I just thought it was all the others cars applauding (with their alarms) the Firebird as we go by... Hmmm? Now your saying John/Bjorn, it's just the 455/3" collectors on the hooker headers, into the Flowmaster Exhaust?
Naw... I like the idea that all the other cars are hoot'n and holler'n at the sight of the Bird! Lol... (what? it could happen!)
