Long story short, tried installing SD headers, completely failed and the car runs like crap. Crossover didn't fit to begin with and tried to make it work, clearly it didn't lol. Downpipe to the cat res was about 2 inches short and now I'm without a drivable car. Anybody know someone in the Port Huron area that could help me out. If so that would be AWESOME. Sorry unnecessary amount of noobness.
