I was wondering if anyone knows any mods avialable for a 2002 Stratus ES with a 2.7L V-6. I'm mostly looking to find new headers but anything that can make my car a little quicker is welcome too. Any help would be greatly appreciated.

You can do this in stages and how much you want to spend. Below are mods and the hp gained.

headers:15-20 hp
free-flow muffler:5-8hp
free-flow cat converter: 10-15hp
Cold Air Injection: 5-8hp
RIPP supercharger: 170hp
