you can find the 4 door one just abut anywhere. i actually just founded for a 2 door. you found find it at ebay, groupbuycenter ( have to ask the greddy peeps) or just search for it. i think it a really good exhaust and its not too loud ( only when u wanna to be loud). its much like the greddy sp but its just with a full s/s pipe. you can read about the greddy sp on carreview.com.
