hmf full system ??

[bigfoot300ex]

i know that there are a million threads about 450r
exhaust but would an hmf full system be a smart choice
to put on a 450r with no mods or would it need more mods besides jetting like airbox mods etc. to really show its power??

i have a hmf full exhaust and i have to say i love it....it has a nice deep sound and gave it alot of bottom end. i also removed my air box lid...im runnin a 168 jet right now but i think im goin up to a 172 or somethin
