Mine took me 30minutes to put in. No tune needed. Just spend the xtra money and get the sfi kit. It uses a one piece crank pulley instead of a two piece. I have the two piece and I'm getting a new crank pulley I don't like the looks of what I have
I'd say 3-400 for everything. Or do it yourself in 3-4 hrs then take it for the alignment. It's not that bad to do with hand tools floor Jack and stands
By the time u spend the money to switch to longtubes it probably won't Be worth it. Lts will cost 3-400 more than shortys then the 5-800 in labor. All for 12-15 hp. If I had to do it again I think I'd go shortys. I lov my lts. But it's alot of work.
