Difference between these slip-ons?

Looking at the MoCo's mufflers for touring models, is there any difference between the Screamin Eagle Street Cannons (#64900186) & the Street Performance Slip On Mufflers (#80721-09), other than the Cannons accept different tips while the others are a slash cut?

I think they are mostly the same, other than the Street Cannons require an end cap.

I think, but am not positive, that the Street Performance slip-ons are 3 1/2 inches and I know that the Street Cannons are 4 inches.

What I am positive about is that I really like my Street Cannons and they have been the most popular slip-on that the MoCo has released lately. (They're constantly on back order from what many here have reported.) They are slightly louder than stock but have a nice low rumble at idle and a good bark when you roll on the throttle. Perfect for touring in my opinion. I posted before and after videos comparing the street cannons to stock in this thread: https://www.hdforums.com/forum/touri...er-videos.html I have about 6,000 miles on them since the install and they have "burned in" and improved since the initial install.

I have the Street Cannons and a friend has the Street Performance slip-ons. We both have a 2014 Street Glide Special. Side by side, his are a little louder and mine are a little deeper at idle and blipping the throttle. I like the Cannons a little better overall because I like rumble.

Necro-post, since I was researching the same thing.
The SE Street Cannon's are nothing more than a glass pack muffler. The SE Street Performance are a chambered baffle design.
