I thought so, there is what I think is a new player out there DNA Performance and they have are making them for street and racing apps and have a line for trucks. Sounds pretty wicked but pricey. Moroso also puts some out, found them on Jegs and Summit. They have sound clips and the street app doesnt sound bad on a Hemi. If the info I've found so far is true, the spiral core almost kills muffler drone.

Well after doing some google search it turns out Moroso does car exhausts too..... new fact learned. I've never heard or dealt with any. Only heard them on quads.
