Hi guys

Will be buying a st 2/3 and just have a couple of questions!

Looking at a 07 plate with 28-40k on could you guys tell me the common faults with these cars have?

What is the best turbo back exhaust to run? Is dream science good to have and was the best way to get pops and bangs like you see so many of these doing what is a good power figure to expect out of these to?

Sorry if this has been asked

Cheers

Lewis
