Hey, as you can tell this is my first post, so I am very proud of it. I'm about to get an 06 si and was wondering if anybody had put in the aem intake, dc header or catback into the car? I'm probably going to do the intake first, and by probably I mean I am. Any suggestions, feedback on what these parts have done?

Also this is the first car I've done anything aftermarket to, so if you have any suggestions for other things I might want to do to it; I'm all ears.

 

I think thomasorallye picked an intake up for his Si...I got an email from him saying it was pretty impressive.
