Piston 4 in. End Caps is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Great looking end cap for Street Cannon mufflers. Purchased these end caps with the Street Cannon mufflers. Considered the other designs. Glad I selected this style . The chrome matches perfectly with the chrome of the mufflers. Note that the tips stick out a little further than the stock mufflers. Looks great on my 2014 Tri Glide. I agree with the previous review that the black inside of the cap works well. Very pleased with quality.

Rated 5 out of 5 by from Looks Better Than Slash Cut End Caps Purchased the billet slash cut end caps to put on the Screamin Eagle Street Cannon mufflers See my review on those. While they looked great they are a little pricey and the polished I.D. of the end caps discolored somewhat once the exhaust heated them up. Additionally, after a while my eyes kept going back to the chrome screws that attach the cap to the adapter bracket. The more I looked at them, the less I liked them. So I tried these piston end caps. Got to say I'm much happier with these. First of all they cost much less. Second, they bolt directly to the end of the muffler so there is no adapter bracket and retaining screws visible. The fit and finish is a notch above the slash cut end caps. Also, the inside of the piston end caps is finished in flat black so no color change once the caps get hot. Wish I had picked these to begin with. I would have saved $. I highly recommend these!
