well i have 150$ and i dont know what to buy for my blaster. i would like to buy a complete pipe but i cant find one for that cheap. but now im looking at buying a set of rear tires because my stock ones suck. so i need holp on what to buy first. if i do get the tires what tires are cheap but will last me the whole summer with alot of road riding. also what size should i get because i also ride in mud and all sort of surfaces. i really want both but im broke right now
