(these were all 2in/2out) My Traid was a work of art and sounded great, but droned so bad it made me deaf. My M&K was alos a work of art and did not drone, sounded great, but was too loud for me. However, it did drone on the next car (SC w/3.0 engine) that it was installed on. My Dansk was not too loud and did not drone, but I didn't like the sound as much as 2in/1out. I'm currently trying out a 2in/2out "pea-shooter" sport muffler . Sounds good, not too loud and no drone, but it still does not sound as good as the 2in/1out, to my ear.
interesting how you say it did not drone on one car and did on another . that is our experience as well do to several things
gear ratio,CR,cams,timing this all plays into the exhaust note.


Oh and compared the dansk is probably the quietest the others are about the same as eachother. You can see that we are developing slide in baffles as well to work for everyone
