What's best performance slip on, (i don't care about how loud it is as long as its not stock). As far as nerf bars, i trail ride mostly, so i don't want the biggest or the smallest, just good bars and gotta look good as well. (some be looking crazy). So long story short i wanting upgrade with slip on and open air box, shoot me your thoughts and advice please.. oh yeah was thinking about wheel spacers because i can't do new A arms because of the high cost, any ideas or thoughts?
