Hey anyone running ARH headers I'm torn between ARH and kook headers I like them both. I here the ARH are long tube and easier to install but have 200 cell cats. The kooks are mid but come with 400 cell cats. I need to pass emissions. (NOVA). I also here that some people have issues with fitment with kook headers??
