Hey! So I've had my 2013 Speed3 for 3 years now with no mods. I live in Orange County and need some guidance first on what to modify first. I want to replace the exhaust, put in a short shifter (possibly myself), and maybe put in a chip. I also need to know about how much it would cost to have someone else do a good job doing these installations rather than myself. I appreciate any responses!
