I have decided I am going to buy an ST-3 in the next month or so. I am really hoping to get the 5 door MK7 as I have a 1 year old with a car seat.
I basically have some questions about modification and security. I don't want to go crazy with modifications, but I was going to upgrade the exhaust with cat back and maybe the intake and shocks. I have tried to search and read up as much as I can but my main worry would be damaging the engine. Can you add these without a re tune? For the exhaust I want something that is a bit louder than stock but with no droning.
Then also I am interested in a quick shift as I heard good things about them. Are they safe to use? I should be able to fit all these myself as I am a trainee mechanic. Or should I drive it as stock for a while?
Then security. What's the best security you can add and what do you guys use?
