A $10 Cherry Bomb glass pack from your local parts store will be loud. My cuz had one on his first gen & it was loud 
I have used Cherry Bombs on every replacement I've done on any vehicle I've owned as long as you are running a cat. They are loud by themselves
Just a few I've run them on,
86 4Runner auto w/turbo
84 pickup
85 pickup
75 Dodge Van
73 Dodge motorhome
I got the shorty on the trucks and the longest they made for the van and the motorhome.
