I have Pypes Violators w/stock cats and sry but I don't hear trucks except for maybe something similar to the 01 Lightning I had. If it can sound like that then I'm fine with it. It sounds fine to me--does drone a bit but WTH. Why get high perf mufflers if u can't take the sacrifices that come with em. Maybe someone can come up with a volume control. If you don't want noise then stay stock/quiet-it sounds OK stock-just needs some volume.. I have Pypes LTs and OR h-pipe on order. Can't wait 'til they're installed and I can make more noise and go a little faster. Just get some decent ones and enjoy the noise. Big boyz toyz make a lotta noize-cuz we like it!
