My car has true dual straight pipe with Vibrant Mufflers at the end. With this setup it was loud, so I added these Moroso to the exhaust, unfortunately it really has not quietened the exhaust at all even with these and the Vibrant Mufflers I see no significant difference in the loudness

Awesome muffler! Not too loud, never drones and sounds mellow and slightly aggressive on my 5.0l SBF in my 1992 f150 in 3” size.

I had straight open pipe on my toyota. It was nasty loud. I added this and it made riding in the car much more bearable. I can't say too much about flow, but from the seat of my pants perspective it seemed to not have hurt performance too much. I thought I noticed a slight loss, but can't say for sure.
