I would like to improve the "yawn" exhaust note without changing the entire exhaust system. Something a little more agressive sounding. Want to avoid cabin drone. Can anyone make suggestions? A bolt on, easy to install, easy to change, solution would be wonderful- but I don't want a full exhaust system change. I also wouldn't mind having some of the black exhaust tips that can be ordered on the AWE system if anyone has suggestions on where to source those. Does AWE sell just the tips?
