I'm very happy with my triad exhaust. To me, it is just right amount of sound. I drive the car for commute / around town residential areas and freeway driving.
Previously had a 2 in 2 out magnaflow setup which was too loud in and outside the car. It attracted way too much negative attention.
Car is 1972 Targa with 1995 3.6l - single O2 sensor
I don't have particularly good pictures, but you get the idea
