Mods for 2001 Accord

What are the most readily available mods for a 2001 Accord v6 EX sedan? I can think of pulley gears, headers, exhaust, intake, and supercharger. Also, what are some good companys for each part?

Headers- Megan Racing or OBX. Intake- AEM CAI or V2. Exhaust-Apex'i or HKS. Pulleys- AEM or Unorthodox Racing. The only person who makes the supercharger for the accords are Comptech. They sell most of the bolt on mods but at a much higher price. Supercharger will cost u about 4g for 60whp.
