    Dialed in to enhance the performance of the Milwaukee-Eight® engine, these slip-on mufflers feature a large inlet for improved airflow. When teamed with a free-flowing air cleaner, these Street Cannon mufflers deliver horsepower and torque gains you can feel.

    • Large 4.5” diameter mufflers are tuned to provide a rich exhaust note, a deep bass rumble, and great throaty sound when you roll on the throttle
    • To strike a balance with your neighbors, the large internal volume and strategically designed baffles help maintain the peace at partial throttle
    • Large diameter body adds a muscular look to your ride, and the newly designed mounts keep the mufflers tucked in close to the bags for a clean profile
    • Features a die-cast Screamin’ Eagle® medallion on their flanks
    • Can be fitted with a wide variety of styled muffler end caps to provide the perfect finishing touch

    Street Cannon Performance Slip-On Mufflers is rated 3.0 out of 5 by 6.
    Rated 1 out of 5 by from Not loud / multiple issues Sadly these are just a touch louder than stock mufflers. Installed these and the high flow intake prior to taking home from the dealer on a brand new 2017 FLHXS. After less than two weeks I noticed a random rattle. Finally after taking into the dealership they discovered a bad muffler where something had broken loose. Dealer replaced under warranty with no questions. As of today 8/30/17 I am going in for the 6th set of mufflers. The last set did not even make it from the dealer to my house before starting to rattle (less than 8 miles). Seriously a waste of my money and more importantly a huge waste of my time at about 2 hours each time I go in for a switch.

    Rated 5 out of 5 by from Deep Growl without being obnoxious These mufflers are a little louder than stock, yet while cruising they just purr nicely. They have a nice deep growl when you hit the throttle and when you decelerate or downshift but they don't wake up the dead. If you want a deep Harley sound without being obnoxious, these are the mufflers for you.

    Rated 1 out of 5 by from Weak I just picked up my bike today after having these put on along with the high flow exhaust and intake, it sounds exactly the same as it did with the stock mufflers. Kind of like riding a vacuum cleaner. Even my wife said that the bike sounds the same as it did. I thought that the shop had inadvertently put the stock mufflers back on, I had to go out and double check. I rode from the shop to a local bike night and one of the guys there commented on how quiet my bike is. He suggested that I take out the baffles. I am sadly disappointed. From a muffler called a "Street Cannon" I expected more. I had Screamin Eagle pipes on my last bike too and they were great, they would set off car alarms when I goosed it.

    Rated 1 out of 5 by from Awful sound They look really nice but the have the worst sound I've ever heard. It's like the stock pipes with a pathetic gurgling rumble. I had screaming eagle on my last bike and they were amazing but these were a huge disappointment. Expecially after the tech told me that they would sound almost the same. Definitely not a harley sound.
