Backfiring is not always undesirable. Cars in storage frequently have
birds or juvenile opossums nesting in the exhaust system, & backfire on
startup cremates & ejects the varmints after they are gassed.
I like to hear an occasional backfire. It's a nostalgic sound that you
just don't hear anymore, what with computer controlled ignition, fuel
delivery, etc. Triumphs, Healeys, & XK Jaguars have *traditionally* had a
borderline cough going hard between the gears.
