I currently have FMF SST's and am thinking of trying some T5's or ?? My question is will I have a noticable performance increase? Other mods on the bike are a dune port/polish, Coolhead w/20cc domes, +4 timing, stock carbs. I only ride dunes but I like to have some low end so I dont think I want a pipe like CPI or shearer. Any suggestions :shrug:
