I'm looking to upgrade my car in lots of ways since its only a V6. i love my car but I don't know any thing about them. I also want to get new rims, Black or crome... I cant decide... im short on money but i need ideas on the cheapest but legit thing to upgrade my car for now. Like a louder engine roar, more HP,maybe some time of stripe decals(i know it dosn't make it faster), just any ideas to my nooby self out

thanks
