I have a '10 FLHTK. Ready to open her up. Going with Jackpot 2-1-2 head pipe to get rid of the cat (I like the stock look too over the V&H and Kuryakyn). Trying to figure out the slip on though. Can't really tell from sound clips on web sites. Also don't know the quality. Any suggestions between these three? Any strong recommendations on any others? Thanks for your help in advance!
