Not Impressed very dissatisfied.

Sorry not impressed at all. They look good, the clamps that come with it will not work on the 2020 low rider s. I had to use the HD ones that came on the bike. one star taken away. The sound factor is good at an idle, when you decelerate on the highway, the mufflers sound like an engine brake on a Semi tractor trailer. Sounds stupid. one more star taken away. Would not recommend them. Even with the db reducers out, still sounds terrible when decelerating. Not a happy biker. :( , don't waste your money.

Great slipons

Look great and sound deeper and louder than stock. Baffles are easy to remove and put back in as well.

Love these slip ons!

Really great slip on option for the M8 engine. I kept the baffles and DB killers in and these are the non-cat version and the sound is just perfect. I leave for work at 5am and I don't feel bad starting the bike up. It's mild at idle but when you're on it they bark! Very nice deep rumble to the exhaust note and the install was super easy. The only loss of a star was for install and that's because the clamps that come with it are thicker and don't allow the OEM heat shields to lay the way they do from the factory so I ended up reusing the OEM Harley clamps. Kudos to S&S for including the gaskets! Fit and finish is top notch as well!

For me these are perfect. Had rineharts but they were just a little too loud and had a bad drone in my full faced helmet at highway speed, don't get me wrong they have an awesome sound. The grand nationals have a nice rumble accelerating and mellow out at cruising speed, almost like factory which is nice. No drone in the helmet either. If you're looking for a middle of the road exhaust in between factory and neighbor haters, these are it.

Good but not great.

They look and sound good but but of the 6 screws that hold the end caps in place two are stripped and not holding tight. They are screwed into very light screen material which strips out on assembly if not extremely careful. Two of mine were stripped when I pulled the end caps out.
