Apologies for hijacking the thread but having just taken delivery of a 2012 from another Talk Mog member I'm also curious about possible upgrades. I am loving the car and it has had most of the recommended safety upgrades over the years so nothing needs urgent attention however it would be great to help the engine breathe a little better. Is drilling out the baffles and adding a better air filter really an option as suggested above or is it better to go for the full stage one engine upgrade?
thanks
Welcome! The topic of exhaust +/-'s is extensively bantered about. In short, a bafflectomy plus free-flow intake will deliver all the benefits to an otherwise stock engine; the others (MMC Stage 1, G56, etc.) are personal sound and aesthetic preferences.
