Loud!!!
This is a really nice system that fit my challenger really good but it'd the loudest cat back I've ever heard. I ended up replacing the bullet mufflers with flowmaster original 40's 3" offset in center out they fit good and sound awesome. I also have jba long tube headers and off road mid pipes I think that helps.
