Looks like a very high quality and complete kit.
Maybe this has been answered before but why would you need to replace any of the stock piping? As far as I can tell, the stock plumbing is just about the best I have seen on any factory turbo car. And I have owned several turbocharged cars. Saturn Sky Redline, BMW 335,
Buick Regal GS, Ford Focus ST: they all have intercooler pipes that leave a lot to be desired.
Are there any plans to sell just the intercooler and use the stock plumbing? I would definitely buy that.
