What would be the best mod for better performance? A header, eibach pro-kit, or custom cat back? I already have a K&N CAI and racing beat axle back. But I can't decide what to do next. Header or springs will bump me up in to prepared class, cat back would keep me in stock class. As far as the custom cat-back, I'm looking at a Magnaflow dual muffler system with custom 2 1/4" piping.
