I'm lookin into getting an intake for my 09 m8, but I already have a y-pipe and can. I've herd from some you need to run a fuel controller and others you dont need a fuel controller. I just want to get rid of the extra weight of the intake on the hood. But I do not want to run a fuel controller. Should I put the stock Y pipe back on and run the intake? Or can I run both. I know this topic has been brought up before but I couldn't find it. Thanks!!
