    50-state legal. Wow! California bikers are happy. Again and again, for engines or exhausts, S&S destroys the competitors.

    Without a complete Dyno readout, there is no way to know if these are any real world improvement or not.

    “California bikers are happy” can’t help but wonder if a second version would make the other 49-States’ riders happier? Glad to see new products, just wondering if S&S will be using CARB as their standard for everything.

    got a 13′ Glide with V&H headers and Thundeheader exhaust. I just slipped through the mandates. Bummer these companies have to spend so much R&D on parts than have less of a carbon footprint then a guy with a hairbun on a fixie.

    Screw these emissions stuff. WTF. Like a motorcycle’s exhaust is going to ruin mankind. Full exhaust systems with headers and NO cats is what is needed on an M8 engine. And NO I’m not some idiotic Trumpster.

    Hi-flow cats have been used in the automobile industry for years while the motorcycle industry has largely lagged behind. S&S looks to be finally bringing this proven technology to the motorcycle space. Powerful and clean? What’s not to like. Well done, S&S.
