Street Cannon Slip-On Mufflers is rated 4.4 out of 5 by 5.
Rated 5 out of 5 by from Super mufflers These street cannon mufflers were purchased as part of complete Stage 1 upgrade for my 2017 Iron 883. The parts included the mufflers, Stage 1 round air cleaner kit and Pro Street Tuner. The parts are all of high quality. I did the installation and tuning myself. The parts are completely integrated, fit perfectly and really wake up the bike. I could not be happier. The bike sounds throaty without being obnoxiously loud. Best of all is how it runs. Throttle response improved at all RPMs and I now have the top end power to cruise well past legal freeway speeds. Plus, I need to compliment HD P&A about the customer service line. I called with a question and the representative was knowledgeable, courteous and really interested in making sure I was happy with the parts and his advice. I would recommend this upgrade to anyone with a similar 883. It will transform your bike.

Rated 5 out of 5 by from Perfect Sound These slip on mufflers were perfect for me. They gave the exhaust a noticeably deeper sound and rumble. They are not loud. If you want loud these are not what you want. They look nice but are not a significant change from the stock mufflers. I also ordered the bronze caps which provides a nice contrast to the black ... it's all a matter of personal preference.

Rated 2 out of 5 by from Yeah....ummm... Not for my XL Picked these up and after three rides knew I wasn't keeping them. Very little difference from stock in sound and performance. Certainly not worth the money in my opinion. Fit is good. What can be said? They're just like the stock mufflers. Inside, the only difference that I could see is that the baffle and the cat are switched around when compared to stock and the baffle is shaped differently. The mounting bracket for the heat shield isn't quite in the right place and as a result, the forward clamp doesn't quite clear the mounting point to connect the muffler to the bike. The hose clamp ends up a little slanted but doesn't affect the overall alignment so it still has a clean line on the bike. Looks like stock without the baloney cut. If you don't have the end caps, the rear is an exposed end that really doesn't look that good. Not sure why they call them shorty because they are about the same length as the stock pipes. Probably longer if you were to add the end caps. "...specifically tuned to deliver an aggressive exhaust note and improved performance..." Sounds just like stock. I didn't have a stock set next to them running at the same time but as far as "aggressive exhaust note," I didn't hear it. Performance difference was unnoticeable. I imagine these with an EFI download might make a difference but stock pipes with a download would probably make a difference too. HD, let's see a dyno chart for these so we can see the "improved performance." So, $459 for the slip ons, $120 for end caps and another $160 for the buckshot heat shields. For about $740 you basically have a stock setup with Screaming Eagle stamped on the heat shield. Very disappointing.

Rated 5 out of 5 by from Not so much louder as better. I was expecting this to sound like the bigger bikes. But it's less pretentious than that. At idle, you get the gurgle and mild pops that the stock pipes are missing. My helmet muffles the sound but pedestrians and drivers notice the bike more at stoplights. At speed, it's a bit louder than stock. But it sounds more like a Ducati than a stock Harley 1200 or 103. It's a good sound a Sportster. I opted for the black slip-ons and end caps but left the stock chrome header shields (instead of getting the black buckshot shields). A bit of chrome is good.

Do I have to recalibrate? Use stock heat shields?

Do I have to recalibrate? I have A stage IV set up. Also, can I use my stock 2016 Roadster heat shields?
Asked by: Dshaw10
Hi Dshaw10, All EFI models require ECM calibration for proper installation. '17-later models require recalibration with Screamin' Eagle® Pro Street Tuner (sold separately). Hope this helps!

When you're just adding the slip-ons, you don't need to recalibrate anything, you are good to go!
