Alright so i don't know much about cars but so far i have a exhaust pipe and a k&n intake installed. Still my car isn't really all that fast. My friend was telling me about headers and how it can increase the horse power. I have about $500 to waste and im willing to try it out but just want to make sure if it's going to be worth the money and the hastle. My friend would be willing to install in so the $500 is just straight for the headers! So can someone please help me on some information about headers! thanks!
