lol yeah that exhaust is for a 2 stroke motor, its either a power core 2 or turbine core get that thing off of there! I got a stock pipe if you need it sparky and all
heat the boot up with a blow dryer and shove that mother in there and clamp it down. over time itll stretch over so you wont have to heat it to get it in
any slip on will give a boost in all power the longer it is the more top end the shorter the more bottom end ,hmf is highly recommended by a lot of guys on here
the only way to lighten it is to take it to a shop I haven't had a problem there are some guys that don't like it because it pulls more top then bottom and trolling through trails is alittle sketchy
