    Street Cannon Performance Slip-On Mufflers is rated 4.8 out of 5 by 128.
    Rated 5 out of 5 by from Great Sound Bought a set of the Street Cannons and 4" Slash tips for my 15 Limited from the Online Store, because, well, I wanted my Harley to sound like a Harley. Installation was super easy, took about 40 minutes start to finish, and the look is fantastic, not to mention the sound. Very nice deep, rich sound, but not too loud, which is exactly what I wanted. The parts guy at the local HD dealership tried to tell me they weren't good, and was trying to sell me another brand of pipes instead, but I wasn't thrilled with the look. Glad I read all the great reviews, because they were right on! I couldn't be happier with the quality, look and sound of the Street Cannons! If you are looking for sound and looks, these are the pipes. Ordering and delivery through the online store was quick and easy.

    Rated 1 out of 5 by from Rip off Bought a brand new fat boy. Apparently this is the only pipe you can buy that doesn’t void your warranty. If you are forcing me with a single choice,make a decent product. Pipes are nearly identical to the stock pipes. Guess I’m voiding my warranty....

    Rated 5 out of 5 by from Good sound and performance. The exhaust is not obnoxious. A good low rumble. Helps to open up the breathing of the stock M8.

    Q & A

    Performance increase?

    I have a 2016 103" Roadglide. How much of a performance increase will these mufflers typically give you? Has anyone who has a stock 103" had a Dyno done after installing these mufflers?
    Asked by: Roadglider2016

    Will the street cannons slip on mufflers fit the new 2017 tri glide and do i need a tuner

    Asked by: pflatout
    Yes and Yes! The part number 64900186B Street Cannons fit the 2017 Tri Glide, and they sound awesome in my opinion. If you want to make sure you're staying within the new Harley warranty guidelines, pickup the SE Street Tuner and cable. There is a Stage 1 download that works perfectly with the 2017 Tri Glide.

    catalytic converter

    I bought a pair of SE Street Cannons because I knew others that had them and they sounded good but not too loud. On my 2009 Roadking, they are quite a bit louder. A look at my stock mufflers and a peek down the head pipe, I realized that there is no catalytic converter in the head pipe but rather in the right stock muffler. So am I nuts or are they louder on my '09 than on a friends '11? Any solution to quiet them down?

    Engine tune?

    I have a 2016 StreetGlide Special, do I have to tune the engine as well? Is it a easy enough job that I can do myself?
    Asked by: Bert70
    You will NOT have to do an engine tune. I have these mufflers installed on a 2014 Ultra Limited and the entire job took about 30-45 minutes. Take your saddlebags off the bike. Loosen the hose clamps that attach the mufflers to the headpipe & twist & turn until your stock exhaust comes off. Be careful not to pull hard. You don't want to scratch any paint. Insert the Street Cannons, line them up for saddlebag attachment & tighten clamps. Finally, attach your saddlebags. Very simple job!

    How much will they stick out past the body on a 2015 Freewheeler?

    Thinking about putting these on a 2015 Freewheeler. Are they longer than the stock mufflers and by how much?
    Asked by: FleshWound
    on my Road King, they stick out the same as the stock mufflers. I added the Short Slash end caps recommended by other riders from this site and quite happy with them. Andy G
