Im new here but I just was hoping to get some honest advice and not people saying things arent worth it. I have a 2010 lancer es 5 speed. I was looking to do more to it without a turbo. I have already added the typhoon air intake and a 3in stainless steel exhaust, I feel a difference however I want more. Any advice on what else would help or any other info would be nice. Also I have the Rockford fosgate system in it and I want to put in an after market Nav system in it. I have seen ones that are andriod based systems so is there any that are affordable and do I need the can bus to install it? Thank you for all the help
