Sound really great, especially compared to stock. Was between these and the TABS, but these are $100 less. Bike runs great with these and K&N filter, no tuner needed.

I was running the Cobra 909s on my 2018 Roadie. Sounded decent, but was missing that classic Harley down shift throatyness. My brother has Rhineharts on his Limited and has a great sound. Just finished installing these and after a quick startup and roll on the throttle, I'm like YESsssss SIRrrrrr..... Can't wait to roll out and get her on the highway!

I listened to a number of different sounding pipes during my research (live sounds…not via YouTube); however, I decided to order these pipes based off of a friend’s recommendation after hearing them on his Harley. Once I had them installed, I INSTANTLY fell in love with the deep, throaty sound and performance of these pipes. Once you roll the throttle, the throaty growl is just what I was searching for; however, these pipes are very “neighborhood friendly” during very low speeds to keep from disturbing my neighbors. I’m very happy with this purchase.

Loved my Rineharts so much and once the wife heard them, she loved them too! So I purchased another set for the Wife’s 2021 Road King! Fit perfect!!! We both think these slipons are PERFECT!!

Money well spent. Make the Milwaukee eight sound like a Harley should sound and they also look great on the street glide special.

Rinehart makes great slip-ons for the Harley if you like a deep throaty sound. Now that I have had the pips on my Road King for over 4 months now, I thought a more thorough review would be appropriate. I added the pipes and a Rinehart air cleaner in November 2021 on my 2019 Road King and I couldn't be happier. You will want to purchase a tuner too. After installing the pipes and air cleaner, I took the bike along with the tuner to my dealership and they tuned it for me. Runs great!Installation took some time, but as an armature mechanic, I did fine. Suggestion, before handling the pipes, I spent the time to use chrome polish which added a protective coat preventing finger stains while installing. Using rubber gloves is a good idea too.Purchasing through Amazon was also great, the slip-ons were out of stock most everywhere but Amazon had them listed and they were in my possession with-in 3 days.

Great quality mufflers from Rinehart. These are quite a bit louder than the motopro45's . I Installed them on my 2020 Road Glide a few weeks after I purchased it while I was waiting for my new cam, pushrods, lifters and headers to show up. They sound great on a stock bike but you will lose quite a bit of torque. They're designed for sound over performance so if you want these pipes to perform as well as they sound they need more back pressure. A set of fuel moto 6" inserts solved the problem. With a proper tune and a good cam these mufflers really shine but all they'll do with taking the extra step is make a lot of noise. Inserts are the key if you're looking for an actual performance gain and not just sound.
