If you're doing the exhaust, dont do just the front pipe waste of time IMO. Just moves the blockage a bit further down the pipe. So do the lot in one hit.
The stock intercooler can handle the hybrid without too much of an issue, but upgrade just because you want to then either the S3 or Airtech are the ways to go.
After that you're starting to look at bigger injectors and a bolt on replacement turbo. Which look on the Darkside website for details.
