I just installed some Cycle Shack Slip On Mufflers, (MXL-130-T tapered). It took me all of about 30 minutes to install. From perusing the various forums, the general issue there was that most folks had a lot of trouble getting the old mufflers off. I had absolutely no problems at all getting these off. Just spray a little WD-40 and yer good to go.

These mufflers are pretty loud but, IMHO, not too loud and they make my Sporty sound more like a Harley should. Cagers will certainly know I am there now.
