just wondering which works best and sound so good?

I didnt feel like spending all that money on a front air dam, so i found a free front end of a 2002 eclipse.  I started to do the whole thing but i messed up the sides.  So got a hold of a fiberglass kit and put just the mouth of the eclipse and left teh factory sides that i had and molded them together.  I was going to do this with some other kit off a car but i got a hold of the eclispe first so i tried it. and i was wondering if there is any kit that comes close to the to the rear that i can
