          Rated 5 out of 5 by from Awesome sound These mufflers are great. They sound awesome with and without the db reducer. Well worth the money. The chrome is bang on.

          Rated 5 out of 5 by from Great sound improvement Bought these to replace the Screamin' Eagle Cannons on my 2013 FLHTK. Running a full stage 2, 255 SE cams, decated manifolds, and SE intake. These pipes came with the baffles already removed and packaged separately. Pipes have a great deep tone and are not obnoxiously loud without the baffles.

          Rated 5 out of 5 by from Great sound and look good! I bought these to get a better sound out of a new stock Harley, M8. The sound is much better. Even with the baffles out, they are not very loud. Louder than stock by quite a bit, but no where near obnoxious. I am very happy with the sound, volume and look.

          Questions

          On S&S website it lists part number for chrome with chrome tracer end cap as 550-0669 but on this site it lists it as 550-0668 but pic shows black tracer end caps. Am I correct in thinking this site description is incorrect but pic is not ?

          Asked by: Matt

          Can you still hear the stock stereo over the pipes?

          Asked by: Fi174
          yes, only gets louder when open throttle up. at cruise mellow. Found a stumble in throttle response with db reducers removed. but smooth with them in. Have stage 1 screaming eagle air filter and tune. Side note: found wind noise (not exhaust) at 110 kph made stereo hard to hear with any clarity so upgraded to stage 1 boom audio, now hear stereo with clarity at highway speeds. Love MK45 look and sound.
