Hi everyone, i just bought a 2016 RS with 2500 miles on it. LOVE IT! I have a Livernois tune already which really woke it up. Looking to see what is another good performance mod. I see Mountune has a sale going on. Are the high flow air filters, charge pipe upgrades, air recirculation valve,... worth it? Was going to do exhaust also but that is more of a sound upgrade. Thanks everyone!
