Performance Mods to an S60R

Hello,

I just bought a 6-speed S60R and I am looking to see if anyone can help me with the choice of modifications to install. As it stands, it has the Evolve body kit, silicon hoses, and Evolve sport exhaust system.

I was wondering which company is better to go with, IPD or Evolve? They both offer the ECU upgrades, intake systems, and downpipes. I am just not sure where to start. Does anybody have any insight?

Thank you very much!
