I went with slp headers because they are ceramic coated and come with everything and bolt right up to the stock cat back. They were 800 bucks tho.... Most on here go with cheaper speed daddy headers and weld in a higher quality flex pipe from what i read. intakes are the easiest mod you can do. Just remove your air box and replace it with a tube and cone filter. I have my cone filter in the fender well for cooler air but many will argue that a filter in the engine bay is just as good. Google zzp, intense, w body store and 3800 performance and look for headers and intakes. Congrats on the new arrival btw
