Also on that note tires are the single biggest upgrade you can make. They are often overlooked as mods as they are not flashy and they don't make noise or power. Adding a set of Nitto 555s to a Scat Pack will make it significantly faster than any other mod I can think of. I have the wider pirelli summer tires from the factory and have serious traction issues now. I couldn't imagine what a Scat is like on the skinny all season tires of the base model it must be a total nightmare to drive.
