shit if u helped me i'd buy u a case lol...but i did a little bit of reasearch on it, and it is a slip on...i had heard about the heat, but i guess there is some heatwrap shit that u put on the exhaust and on the ecu thats suposed to help, but im not too worried about the sound, although it does attract more attention, a buddy of mine had the same exhaust on his bike just not with the plastic tail piece, and i loved how the bike sounded
