i wanna no what u guys think i should put on my 300ex next i was thinking either a new silencer or a jet kit and air filter...it wont be put on for like 2 weeks though cuz i need the cash but i wanna no what to save up for first

 

for the most power put a full exhaust (will make it loud ) Then a jet kit is what I did and it worked then an air filter any of those in any order realy but i would suggest If you havent al ready to widen the atv front and rear if not both atleast front i did this just the front and it helped the quad from wheeling up when you gas it a good brand is here i got the 6in and i helped tons and is plenty strong for huge jumps.

04 400ex
white brothers e-series megaphone full exhaust
k&n filter
Dynojet jet kit
6in front widening kit (diamondjcustoms.com)

 

whats the best system for my 300ex then i was thinking the curtis sparks or white brothers

 

or a yoshimura slip on
