Flowmaster Delta Flow 50's - 1968 Firebird

[RAFO9A]

Just wanted to share the exhaust sound of this exhaust system. As far as sound quality is concerned, the rumble is noticeable at idle but not intrusive. I can talk to passengers without issue. I did have a drone at first, but eliminated it by adjusting the idle to 600 rpm. During cruise (1500 - 1900 rpm) it's quiet and undetectable, but can be heard at part- heavy- and wide-open throttle.

Here are the pics of the install:
