Right now I'm running stock. I don't have a lot of disposable income at the moment but I had been considering getting the following in this order:
- AEM Cold Air Intake
- HFP exhaust
- FD2 rear bumper cover and shave trunk keyhole and badge
- FD2 side skirts
- FD2 front conversion with CSX headlights
- HFP suspension for Si
Unless they can figure out the clanking coming from the front driver's side of my car though, I may try the HFP suspension first to see if that can get rid of the noise.
