Does your X-pipe exhaust drone loudly?

My friend has a 74 duster with a 360 headers. i honestly dont know what crossover pipe it has. but anyway he had 3 inch pipe to 2 thrush welded mufflers with turn downs at the axle. The car droned like all hell. He got some tailpipes and now its lots better. The only complaint he had is he cant set off car alarms now.
