They sound pretty good, but a too "unrefined" for my taste. And if off road exhaust, going to be WAY too loud for the street. At least if you want to be able to talk to your passenger...
I run 2 chamber flows/off road exhaust, and at times it is too loud...
several of my friends had them on the fox cars, wayyy to loud for me. had a, testicles to the sheetrock type of sound, just all in ya grill peice. if thats the note going going for, do it. but its NOT a subtle exaust note, thats for sure.
