i've heard that HMF are great pipes and do the job well. my friend has one on his Cannibal and he loves it. i'm not sure specifically for the 300 if the power increases greatly but it should definitly have a good boost. you definitly have to rejet if you get a pipe or it will just sputter and stall and do weird stuff.

t-4 is greatness :p i love mine. my friend has an hmf on his 400 i hate how it sounds. yuck! but my t-4 is awsome. i didn't even jet and it runs perfect and you can feel the difference and it sounds great low rumble kinda like a 400 with a big gun full system.

prvt maggot i wanted a t4 but they dont make them for my quad i think. i also dint think i had to rejet with just a slipon

yeah you will have to re jet it, but its kinda hard to find the best spot when doing it
