I love my Chin Spoiler look here

This is cheap and you can put it on with a drill and a screw driver. If you can't be fast, you can look good. And there are a lot of non-ricer type accessories. You can still beat some of the 4 cycl imports and the GM low power V6's.... Alero, V6 Camero etc. and look good too.
Otherwise, I agree sell the V6 and drop back a few years and buy a mid-late 90's GT or Cobra. That is the cheapest way to get more power quickly. The gain in power is very substantial even with a GT. Cobra would be even better.
