I've recently started getting into mods for my 2011 Volvo c30. Still a noob here, but just wanted to get an idea of what people are doing with their cars. So far, I have the following installed: 1. HID lights (from ddmtuning) 2. Hella supertone horns (these horns are extremely loud) 3. 3" downpipe (from Elevate) 4. Software ECM remap (from Elevate) 5. K&N Typhoon intake (this sucker sucks air like a jet engine) Next steps are going to be the rear sway bar, inlet manifold and maybe the front-mounted intercooler.
