Your car wont be very loud since you still have 4 cats on it. you dont have to worry about getting oulled over, my 85 vic has longtubes and Flowmaster 50's, and dumps. loud as hell and cops dont even look, even when i had the 40s on it they never cared.
yeah i've checked out other crown victorias with flowmasters on cardomain and one guy had a video of the 40 series and it wasn't real loud but it still had a mean idle , and when he accelerated it sounded real nice... and i heard the owner of the shops grand marquis that im getting my exhaust done at , his is fairly loud (not super loud) I dont think he had any converters taken off, you can hear his marquis go by you when your windows are up...
I dont want to get pulled over by the cops but i do want to hear SOMETHING lol, if it's not loud at all I might look into taking 2 catz off but i doubt it because from the crown victorias/marquis i've heard they sound good not 2 loud and not 2 quiet.
