Honda Civic Forum - My Womans Car

My woman just puchased a used 04 Civic EX. She all ways complains about my spending habits when it comes to my car, so I figured I would get her some stuff, so she can shut the hell up. I'm interested in CAI, Headers with or w/o high flow CAT(preferaibly CEL friendly), Catback system (preferibly not too loud, and with min. highway drone), and a Short Shifter.
After reading the stiky threads, I've concluded that 5Zigen Fireball, RS-R ExMag, and Apexi WS seem to be generaly quiet w/ some moderate power gains (not that the woman cares too much about power). As far as header s go, DC & HP seem to be the forum choice, but are there any others out there? CAI pretty much all the same IMO. Short Shifters, non-adjustable/adjustable?, manufactures?, what's out there? Any personal opinions, thoughts, or expearience would be great.
