I too have the non resonated touring. I've heard several different aftermarket systems 1st hand and the AWE Imo sounds the best. No drone at highway speeds and screams when you get on it.
The diamond black tips are epic and very large. For me, they are very tasteful without all the Borla cutout stuff.
Originally installed with link pipes and tried removing them to deal with excessive popping during engine start . Didn't help, so I put them back on. I'm guessing a tune will be the only thing I can do to eliminate that? It scares everybody lol.
100% satisfied with all aspects of this system.
