Hahaha, Good ole' scented pine tree. Pretty much the cheapest overall mod for the 6 is gonna be overlays for your darts. You can get them from grafxwerks.com for 15 dollars shipped for the front and rear dart. I also did LED's under my front dash for about 25 dollars, from autozone. As far as performance goes, probably a K&N drop in filter for around $50. The K&N website boasts a gain of 1-4 HP for this product.
OH, and you can de-badge for free, if its hot enough outside.
