i have a stock 99 400ex been wanting to buy a pipe but dont feel like getting a full system so i want a slip on. ive heard nothing but good things about motorworkssr4.-209$ but ive seen a lonestar slip on for 235 and a trinity slip on for 250. wanna keep the pri ce under 300. i dont want a hmf beacuse i want a nice beefy tone not blow youre eardrums out. i used to have a white bros e series om my 300ex but and i loved it. i was also looking into a r4 white bros but cant find one. so anybody feel free to put youre ups and downs on these pipes. and if youre gonna bash on diff pipes take youre 2sense elsewhere. thanks!
