I don't have headers yet but I did get rid of the cat and I have super traps and no cross over muff anymore and I just love the sound

I just got rid of my dual cats and have a flowmaster 80 series with a cutout. I cant leave the cutout open anymore because it is way too loud without the cats. my flowmaster sounds much better than before though.
