Well i new here and this is my first post so here it goes

I have a Yamaha Raptor 250 and i just got a new set of tire and nerf bars. Now im looking for power, i want to get a new air filter and a new exhaust but dont know where to start. I have been looking at big gun evo R complete exhaust kit for it and maybe a gytr air filter but any advice i would take into consideration. Point me in the right direction here on sizes and wrongs and rights for these things.
Thx

 

I run a uni filter and sparks exhaust. With any of those mods you will have to rejet. If you don't rejet you just wasted your money on those items plus it will run hotter. I'm not too familiar with the 250. Does it have a closed airbox or an exposed filter?
