Street Cannon Performance Slip-On Mufflers is rated 4.9 out of 5 by 12.
Rated 5 out of 5 by from Street Cannon Performance Slip-On Mufflers Purchased 2017 Ultra Limited with these and SE High Flo. Awesome sound at idle with rumble when giving rpm's. Previously had Vance & Hines Big Shot Longs on my Heritage (Big Sound) and wanted to downsize, but still wanted the Harley sound, these provide it. Very pleased with them and highly recommend.

Rated 5 out of 5 by from Great sound when you want it, not obnoxious when cruising Purchased a 2017 CVO Limited and had these Street Cannons installed ... at first I wasn't too pleased with them, but as both the bike and the exhausts break in they sound nice ... not obnoxious when cruising to the point where they put you in the back of the pack 'cause no one wants a headache but still have a great sound when you get on the throttle, plus they look awesome with those big tubes coming out under the saddlebags. A recommended upgrade from stock, even though the CVO is already an upgraded machine these are a nice subtle addition. Very happy with them, so are my riding Buddies and my Wife.

Rated 5 out of 5 by from Street Cannon Scream'n Eagle Great quality finish, packaged nicely when shipped. If you want the Milwaukee 8 to sound like the older engines, these muffler will not do that for you. The mufflers give a slightly deeper sound at idle but have a nice deep sound under acceleration. Nice sound while cruising. I installed along with Scream'n Eagle air cleaner and street tuner. Very satisfied.

Rated 5 out of 5 by from Tuned for nice 80db idle! Went from 2015 Low Rider with Vance and Hines Long Shots to 2017 Ultra CVO with Vance and Hines header with Screamin eagle slip ons. Decent sound at idle. Really opening up when you twist the throttle. Best of all nice while cruising.

Street tuner calibrations

Hi, I'm still interested in getting my question answered from an actual HD Tech since my dealership left me confused. Pilgrim's answer is not what I'm looking for, I already knew everything stated there, nor do I want the K&N stage 1 filter kit. Don't care for the maintenance of them or the sucking air intake noise they produce. I prefer the SE synthetic media filters but apparently not being provided anymore for the M8's. All I wanted was slip-ons with the calibration for those that HD leads people to believe is available but being told there isn't one. Specifically I need to know why Harley describes the Street Canon mufflers as needing an ECM recalibration when installing mufflers only, yet apparently doesn't provide a calibration in the street tuner for that, only one for Stage 1..this is what my dealer told me. My concern is doing the Stage 1 calibration is changing the settings that were developed based on expecting a certain amount of air increase, but when leaving the stock intake in place it doesn't get that increase. This to me implies that it is now not tuned properly and that is not acceptable to me if true. I have no interest in dyno tuning to correct this. I would not have bought these if the information wasn't so ambiguous. This needs to be made clear from the factory.

need HD tech ECM recalibration help

so I bought the street canons and street tuner for my 2017 Road King...dealer did the recalibration and said there is not one specific for just the mufflers only a Stage 1 calibration, even though I kept the OEM intake on. He said there is a broad enough range from the oem intake to the high flow stage 1 filter kits that the calibration will accommodate either..Is this right? sounds fishy, don't want to have a tune that isn't meant for my components..thanks
Asked by: Kell
This bike and engine are brand new so I suspect he did the best he could. The stock filter is 1/2 the size of the high flow that fits in the stock housing, but HD made it plenty big enough for this engine to breath. If anything you might run a bit rich and richer as the filter gets dirty. The Cannons are straight through but you still have a Cat infront of them. You also have 2 O2 sensors that the CPU monitors and makes adjustments. Usually doing just the exhaust or just the intake you wouldn't need a tune on any bike. Once the CPU has been programmed your stock program is lost so you can't put the factory program (stock) back in. (A dealer might) I did my Stage l myself and used the pro steer tuner myself. I saw no way to save the stock tune. All that being said I'd just ride it and check the plugs ina thousand miles. Ask Santa for the high flow intake for XMASS.
