full bolt ons

I have a 2008 MazdaSpeed 3 Cosmetic Blue 52k miles on it, just got it a couple months ago with 48k on it. There was no mods done to it, I'm not loaded with money so I'm slowly adding to it. So far I have a Cobb SRI and Turbosmart SU Bypass Valve, and I installed a Defi Boost Gauge in my drivers...
